Antimicrobial compositions and associated methods of use [0001] This application claims the advantage of the priority of American application serial number 1'3 / 815 839 filed on March 15, 2013, which is incorporated herein by reference in its entirety.
Background of the invention.
Significant progress has been made in the identification and development of biocides to control different molds, plant pathologies and the like. However, most of the commercial biocides or pesticides used are compounds which are classified as carcinogens or which are toxic to wild fauna and flora and other non-target species. For example, methyl bromide is widely used as a soil drainer and in the postharvest treatment of microbial infections. Toxicity to humans and adverse environmental effects will ultimately result in the discontinuation of the use of methyl bromide and various other synthetic biocides / pesticides. Consequently, recent efforts have focused on the identification and development of natural or biomimetic compositions revealing a comparable antimicrobial or pesticidal effect.
Such an approach relates to endophytes and associated volatile side products. Endophytes are defined in the art as microorganisms that reside in the interstitial spaces of living plant tissue, but they are generally not considered to be parasitic. In particular, endophytes discovered in association with rainforest plants have aroused considerable interest for reasons related to the antibiotic nature of their volatile side products. Several members of the geme Muscodor (namely, M. albus, M. roseus and M. vitigenus) have been shown to produce volatile side products revealing an antibiotic or insecticidal nature. However, the respective by-product of each species contains various derivatives of naphthalene and / or azulene. Such compounds, as well as other components of by-products, can be toxic or otherwise unhealthy and the corresponding mixtures are considered to be unacceptable for various end use applications. Therefore, research is continued in the art to identify natural compositions and develop mimetic compositions free of these compounds, which are harmless for human use and reveal effective antimicrobial properties.

Some of these plants and / or some of these products are recognized in the art, alone or collectively, as agricultural crops. Therefore, in certain embodiments, a composition of the present invention can be over or applied to a crop at any time during its development, before harvest and / or after harvest. Likewise, a composition of the present invention can be applied to or incorporated into a drink, a food product (eg, intended for humans, domestic animals and / or animals) or an article of manufacture which can maintain, is capable of nurture or maintain microbial growth.
[0053]. In certain other embodiments of the present invention, such a composition may be on, or as it may be applied to, a substrate or surface supporting or encouraging the growth of a microbe (for example, yeast and / or fungus bacteria and / or virus). Consequently, such a substrate or such a surface can comprise any material which can maintain, is capable of maintaining or violates the .1.4 .MA
38484Β1 microbial growth. Such substrates include but are not limited to wood, ceramic, porcelain, stone, flat, drywall, cement, fabric, leather, plastics and the like.
In certain other embodiments, different compositions of the present invention can be on, in contact with, or as applied or administered to a substrate or surface comprising mammalian or human tissue, including but not limited to , nails, hair, teeth or mouth, skin and other cellular material, in the context of a pharmaceutical presentation or personal hygiene or hygiene for the treatment or prevention of microbial growth or infection.

An endophytic fungus was removed from the tissue of a wild pineapple (Ananas ananassoides) which grows in the Bolivian Amazon. Finally, it has been shown to produce a mixture of volatile compounds with antimicrobial activities. Using molecular techniques, it has been observed that the fungus has sequence similarities with members of the genus Muscodor. These fungi are known to produce volatile organic compounds that can act as antimicrobials that are effective against both human and plant pathogens. Members of the Muscodor species have been identified using methods such as phylogenetic character mapping using 18S rDNA and ITS-5.8S rDNA sequence analyzes. The sequences found in the present fungus and other Muscodor species have been researched by BLAST in GenBank and compared with other fungi (Bruns et al., 1991; Reynolds and Taylor 1993; Mitchell et al., 1995;
Guarro et al., 1999; Taylor et al., 1999). Finally, these isolates were determined to be related to Xylaria (Worapong et al., 2OOla & b) ٠ All isolated taxa that belonged to Muscodor had similar characteristics, such as relatively slow growth, possession of a similar mycelium to felt, the production of biologically active volatile compounds and the fact that they did not harm the plants in which they originally resided. Finally, they all share very similar rDNA sequences (Ezra et al., 2004).
Although the present fungus shared all the same common characteristics mentioned above, there were a number of different aspects compared to the taxon which distinguished it from all other Muscodor species and other isolates. As illustrated in more detail in the following examples, these
MN
38484Β1 unique characteristics support the establishment of the present fungus as a new species. The name proposed for this new endophytic fungus is Muscodor crispans.
According to the CG / SM analysis, the isolated fungi produced alcohols, esters and acids of low molecular mass, in the gas phase, when they were grown on dextrose potato agar ( PDA). As shown in Table 1, below, these compounds include propanoic acid, 2-methyl;
1-butanol, 3-methyl, acetate; 1-butanol and ethanol. No naphthalene or azulene derivative (non-GRAS compounds) was produced by this organism when cultivated on PDA, which distinguishes it from all the other Muscodor species studied so far. The odor produced by the fungus becomes noticeable after about 1 week and seems to increase over time up to and for at least three weeks. As illustrated below, the volatile products of this fungus have inhibitory and lethal biological activity against a number of plant and human pathogens using the conventional bioassay technique (Strobel et al, 2001).

Alternatively, a wide range of natural and synthetic biomimetic compositions can be used with a comparable or improved effect or, as evidenced by one or more embodiments, to provide results not previously available with use either the fungus or its volatile byproduct. As a departure from the prior art and the secondary product of M. crispans, such antimicrobial compositions include food and flavoring compounds generally recognized to be harmless for human use and consumption. To illustrate this, several nonlimiting biomimetic compositions are provided in Tables 2 to 7 below. Various other compositions may include combinations of compounds selected from one or more of Tables 2 to 7 (see, for example, Examples 52 to 56). Alternatively, such a composition may include a component compound in addition to or in replacement of any of the listed compounds, to improve volatility or modify any other end use or performance property. In some of these compositions, such a replacement or additional compound may have a GRAS designation and / or be thus designated at the levels used; these compositions as they can be considered essentially free from any component or material which would not be generally recognized as harmless (GRAS) according to the code "United States Code of Federal Regulations". Such compositions may, alternatively, comprise a component found in a volatile side product of M. crispans and / or not in a volatile side product of another species of Muscodor.
Each of these compounds can be provided in an effective concentration or a range of percentages and is either commercially available or can be prepared by those skilled in the art. Regarding this last point, fermentation techniques can be used to naturally prepare and isolate these compounds. Alternatively, such compounds can be synthesized chemically. Compared to several non-limiting embodiments of the present invention, each compound of Tables 2 to 7 can be obtained as a fermentation product, these products and corresponding compositions as they are available under the trademark Flavorzon from Jeneil Biotech, Inc. from Saukville, Wisconsin.

Example la [0099] 'Fungal isolation. Several small stems d<sup>,</sup>Ananassoides pineapples were taken from a plant that grows in the Bolivian Amazon in March 2007. They were harvested in a savannah region at the edge of the rainforest at 12٥40'07 s and 68٥41'58 W and they were transported immediately to be analyzed. Several small pieces (2 to 5 inches) of the stems were cut and placed in 70% ethanol for 30 seconds under a laminar flow host. A pair of sterile fine forceps was used to hold the stems separately in the flame to extract excess alcohol. Then, small pieces of internal tissue (under the bark) were excised and placed on agar
Γ. μα 38484Β1 potato dexfrosee (PDA) with an actively growing isolate 620 of M. albus on one side of the dish fr om which a central well has been removed. In reality, this technique can be used to select other Muscodor isolates (Worapong et al., 2001a & b). During an incubation period of two weeks, the Petri dishes were examined periodically for any fungal growth. Once hyphae were observed, the tips of the hyphae were septically cut from the agar and placed on fresh PDA. The isolate was obtained in this manner. Several Petri dishes (PDA) were used to determine if the fungus produced volatile antibiotics. This procedure included the steps of extracting an inch-sized section of the agar from the middle of the dish, spreading a nut of the isolate on one side and letting it grow for several days, and then spreading the test organisms on the other side of the opening.
Example lb [0100] Fungal taxonomy: the fungus by its nature is associated with A. ananassoides and it is a deuteromycete belonging to the order of mycelia sterilia. Whitish fungal colonies on all tested media when left out of direct light. Rosary fungal colonies on all media tested when exposed to direct light. No spore or other fruiting body was observed under any of the conditions. Hyphae (0.6 to 2.7 µm) commonly grow by branching, sometimes forming perfect coils (about 40 µm) and having bodies similar to cauliflower (3.5 to 14 µm) associated with them. The hyphae, which begin to develop, grow in an undulating pattern when they are observed in all conditions with all the media tested. The mycelium on the PDA covers the plaque in 3 to 4 weeks and produces a fruity odor.
Holotype: endophyte on A. ananassoides. Harvests have been made in the Bolivian Amazon in the Heath River region. The holotype comes from a single stem of A. annisoides, harvested in the Heath River country. A living culture is deposited under the name Muscodor crispans in the living mycological collection of the State University of Montana under the acquisition number 2347 (2/29/2008). The 18S rDNA and ITS (internal spacer arm transcribed) sequences of M. crispans (Β-23) were both delivered to GenBank under the assigned serial number -EU195297.
Teleomorph: the teleomorph of this fungus can be found in Xylariaceae, based on the similarity of the 18S rDNA genetic sequence data between M. crispans and the family Xylariaceae in the GenBank database (Bruns et al., 1991; Reynolds and Taylor 1993; Mitchell et al., 1995; Guano et al., 1999;
MY
38484Β1
Taylor et al., 1999). The molecular data of the 18S rDNA genetic sequences of
M. crispans reveals a 100 ٥ / o homology with isolate 620 from M. albus.
Etymology: the name of the genus, Muscodor, comes from the Latin word which means musty. This corresponds to the quality of the odor produced by the first three isolates of the genus. The name of the species is crispans, from the Latin meaning "curved, wavy". The hyphae grow in regular wavy patterns.
Example 2a [0104] Scanning electron microscopy. Scanning electron microscopy was performed on the isolate of Example 1 according to procedures described by Castillo et al. (2005). Pieces of agar and pieces of the host plant serving as support for fungal growth were placed in packets of filter paper and then placed in 2 ٥/٥ glutaraldehyde in 0.1 M sodium cacodylate buffer ( pH 7.2 to 7.4) with Triton X 100, a wetting agent, aspirated for 5 minutes and left overnight. The next day, the pieces were washed with 6 changes of water and 1: 1 buffer of 15 minutes, then a change of 15 minutes in 10% ethanol, a change of 15 minutes in ethanol at 30 ٥/٥, a 15 minute change in 50% ethanol, five 15 minute changes in 70 ٥/٥ ethanol, and were left overnight or longer in ethanol at 70%. Then they were rinsed six times for 15 minutes in 95% and then three 15-minute changes in 100% ethanol, followed by three 15-minute changes in acetone. The microbial material was thoroughly dried under critical conditions, spray coated with gold, and samples were recorded with an ESEM FEG XL30 in high vacuum mode using the Everhart-Thomley detector. The hyphae were measured using Image ل software available online.
Example 2b [0105] Fungal biology. The fungus produces a white mycelium on a water-based support. No fruiting structure or any kind of spore was observed under laboratory conditions. The hyphae tend to form curls. Other Muscodor species also have this tendency (Worapong et al., 2001a). The hyphae that are beginning to develop tend to grow in a wavy form rather than the typical straight pattern which intertwines curving up to form rope-like structures. This growth model can be useful as a diagnostic tool to identify this organism in in vivo inoculation studies. The fungus also produces cauliflower-like structures that appear to be
٢٦٢
38484Β1 connected to the hypha by small strands. These bodies do not germinate under any of the conditions and do not appear to be spores. This observation seems to be unique for Muscodor spp. and it has not been noted as being present in other fungal species in general.
Example 3a
101061 Fungal growth and storage. The isolate was determined not to produce a spore or a fruiting body when several pieces of carnation leaves were placed over a pushing activating isolate to encourage spore production, and none of these sfructres was observed after a week of incubation at 23 ٥c.
The fungus was also spread on several different media including cellulose agar (CA), malt extract agar (MA) and corn flour agar (CMA) to determine if the spore production would appear. With the exception of slower growth in some of the environments, no other characteristic of the fungus seemed different and no fruiting body or spore was observed.
Several methods have been used to store isolated mushrooms as a pure culture, one of which was the filter paper technique. The fungus was allowed to grow on PDA, and then it was cut into small dice which were placed in vials containing 15% glycerol and stored at -70 ٥c. The mushroom was also stored at 4٥ C by a similar process, using water instead of glycerol. However, the most efficient method of storage was on sterile barley seeds infested at -70 ٠c.
Example 3b [0108] Other more conventional characteristics of the isolated M. crispans were also examined and compared with M. albus. Muscodor crispans produced a dense white mycelium which grew slowly on all the tested media, except when placed in direct light, which caused the mycelium to develop a pink color. This contrasts with
M. albus which produces a whitish mycelium on all comparable media and under the conditions tested (Worapong et al., 2001a). Young hyphae also grew in a wavy, rather than the characteristic straight, cable-like manner as is commonly observed with M. albus (Strobel et al., 2001). No spores have formed on
The hyphae were of different diameters (0.8 to 3.6 µm) and often intertwined to make more complex structures and even windings of hyphae (Figures 1 to 3). These hyphae were generally larger than those of M. albus (Worapong et al., 2001a).

101091 Qualitative analyzes of volatile products. The method used to analyze gases in the airspace above a day culture of mycelium growing in Petri dishes was comparable to that used on the original isolate of M. albus strain cz-620 ( Strobel et al., 2001). First, a heated “solid phase micro-extraction” syringe (Supelco) consisting of 50/30 divinylbenzene / carburen on polydimethylsiloxane on a stable flexible fiber was placed through a small hole drilled in the side of the growing Petri dish fungal. The fiber was exposed to the vapor phase of the fungus for 45 min. The syringe was then inserted into the slitless injection port of a Hewlett Packard 6890 gas chromatograph containing an ID ZB Wax capillary column of 30 m X 0.25 mm with a film thickness of 0.50 mm . The column temperature was programmed as follows: 30 ° C for 2 min then 220 ° C at 5 ٠c / min. The support gas was ultra-high purity helium (local distributor) and the head pressure of the initial column was 50 kPa. Before trapping volatile products, the fiber was conditioned at 240 ° C for 20 minutes under a flow of helium gas. An injection time of 30 seconds was used to introduce the fiber sample into the GC. The gas chromatograph was interfaced with a mass selective detector 5976 from Hewlett Packard (mass spectrometer) operating in unit resolution. Data acquisition and data processing were carried out on the Hewlett Packard ChemStation software system! The initial identification of the compounds in the mixture of volatile products produced by the fungus was carried out by comparison with a library using the NIST database.

An evergreen culture of the present fungus, growing on PDA, was used as the DNA source after incubation at 25 ° C using! Rapid homogenization: Vegetable DNA amplification kit! (Cartagen; Washington,
USA). Some of the techniques used were comparable to those used to genetically characterize other isolates of M. albus from Australia (Ezra et al., 2004). Cultivated mycelium cubes (0.5 cm<sup>2</sup>) have been cut out from week-long cultivators. The agar was scraped from below the pieces, to exclude as much agar as possible. The pieces were placed in 1.5 ml Eppendorf flasks and incubated for approximately (my
38484Β1 minutes at -80 ٥c. Then, the DNA was extracted according to the instructions of the kit manufacturer. The extracted DNA was diluted (1: 9) in sterile, double-distilled water, and 1 μΐ samples were used for amplification by PCR. The rDNA sequence ITS1, 5.8S ITS2 was amplified by the polymerase chain reaction using the primers ITS1 (TCCGTAGGTGAACCTGCGGG) and ITS4 (TCCTCCGCTTATTGATATGC). The PCR procedure was carried out in a reaction mixture of 14 μΐ containing 1 μΐ of DNA extracted from the fungal culture (dilution 1: 9), 0.5 μΐ of ITS1 primer and 0.5 μΐ of ITS4 primer, 7 μΐ of RedMixTM plus the PCR mixture with 1.5 mM of MgCl (GeneChoice, Inc., Maryland, USA) and 5 μΐ of ddHO of PCR quality (Fisher Scientific, Wembley, Western Australia, Australia). The PCR amplification was carried out in a Biometra personal cycler (Goettingen, Germany): at 96 ٥c for 5 minutes then 35 cycles of 95 ٥C for 45 seconds, 50 ٥c for 45 seconds and 72 ٥c for 45 seconds, followed by a cycle at 72٥c for 5 minutes. The PCR products were examined using gel electrophoresis, on a 1.3% agarose gel for 30 minutes at 100 V with TAE buffer (GelXLUltta V-2 from Labnet International, Inc., ( Woodbridge, NJ, USA) or a GES cell system from Wealtec (Wealtec Inc., Georgia, USA). The gels were soaked in 0.5 pg ml-1 ethidium bromide solution for 5 minutes and then washed in distilled water for 5 minutes. The imaging of the gel was carried out under ultra-violet lighting in a Bio-Imaging system (model 2O2D; DNR-Imaging Systems, Kiryat Anavim, Israel). A PCR product of approximately 500 bp was purified using the UlttaClean PCR Clean Up DNA purification redhead (MO BIO Laboratories, Inc., California, USA). The purified products were sent for direct PCR sequencing. The sequencing was carried out on the two strands of the PCR product using the primers ITS1 and ITS4. Sequencing was performed using DYEnamic ET terminators on a MegaBACETMlOOO analysis system (Danyel Biotech Ltd., Rehovot, Israel). The footage was submitted to GenBank on the NCBI website. The sequences obtained in this study were compared to the GenBank database using BLAST software on the NCBI website.

Example 6a Biological assays for M. crispans against plant pathogens. The vapor of the volatile by-product of M. crispans was tested for the inhibitory activity against microbes using a relatively simple test, as described previously in the literature (Strobel, et al., 2001). An agar strip (2 cm wide) in a PDA Petri dish was removed and M. crispans was inoculated and left to grow on one side of the box for a week. Then the test fungus or test bacteria was inoculated on the other side of the Petti box, using small agar nuts for the mushrooms. The bacteria and yeasts were deposited in continuous bands on the agar (1.5 cm long). Then the box was wrapped with a piece of Parafilm and incubated at 23 ° C for 48 h. The effect of M. crispans on the growth of test organisms was determined first by verifying the presence or absence of growth where the inoculations had taken place. If growth was observed, diameter measurements at the two locations of the fungal hyphae were taken. The biological activity of the vapor on bacteria and yeasts was evaluated by estimating the extent to which their growth had been affected as a percentage of growth on a control dish (Sttobel et al., 2001). If no growth was observed, the test organism was aseptically removed from the test dish and inoculated on a dish of fresh PDA at a given time point after exposure to steam to determine viability. of the test organism.
٠ΜΑ 38484Β1 Using the above methodology, after M. crispans has been cultivated for 7 to 10 days at 23 ° C. on PDA, the volatile byproduct of the fungus has proved to be lethal for several fungi and bacteria. Gram negative and gram positive bacteria, as well as yeast and each of the major classes of fungi, were used as test organisms. Most test organisms were 100% inhibited and would die after 2 days of exposure to the byproduct of
Mr. crispans. (see Table 8). Some test organisms did not succumb to the volatile products of M. crispans after two days of exposure, but their growth was significantly inhibited by the volatile byproduct and they died after four days of exposure. Such organisms include Penicillium roquefortii, Bipolaris sorokiniana, Stagonospora sp., And Fusarium oxysporum, among others.
Table 8. Effects of the volatile side product of M. crispans on many fungal plant pathogens and some different bacteria. The inhibition values were calculated as the inhibition of growth in% relative to an untreated control test organism. The tests were repeated at least 3 times with comparable results.
The inhibition of the test organisms was recorded 48 hours after exposure to the fungus and to the vapor of the volatile fungal by-product.

Example 6b With reference to Table 8, the effect of the vapor of the volatile secondary product of M. crispans on gray rot is quite remarkable, in particular on 5. cinerea, which is the cause of gray mold on various plants. The inhibitory and lethal effects also apply to Botrytis went to the origin of the gray mold of the rot of the collar of the onion. Without limitation, such results suggest that the present invention can be used effectively to modify the surface area of the product or the post-harvest storage atmosphere to prevent mold and associated problems. Likewise, these results support the use of a composition with CAA of the present invention to treat products such as onion (for example, Vidalia onions), shallots and garlic to prevent or control growth. fungal.
EXAMPLE 6c The vapor of the volatile products of M. crispans is also effective against many fungi which cause decomposition and fungal growth on cereals (for example, corn, wheat, barley, rice etc.), and present it. The invention can be used in combination with various fruits and vegetables such as potatoes, beets, carrots, sweet potatoes, such cereals, fruits or vegetables, before or after harvest, during storage or shipment. Therefore, the compositions and methods of the present invention can be applied to some of the major fungal problems in the fields of agriculture and food processing, and can be used to target organisms such as, but without limitation, Alternaria, Cladosporium,

Such results suggest that the compositions with CAA and associated methods of the present invention can be effectively used to treat seeds, seeds, orchards, equipment or apparatus (including, for example, workers' equipment and clothing) and / or fruits harvested to prevent, inhibit or control canker disease.
EXAMPLE 7 In the context of monitoring the tests and results of Example 6, biological tests with the vapor of the volatile secondary product of M. crispans were carried out with various other fungi and bacteria which are pathogenic in plants and humans ( see. Table 9, below). The fungus was cultured on X-dishes with PDA in a quadrant and incubated for 3 to 5 days at room temperature before inoculation with one or more test organisms. Control dishes were made at the time of inoculation and cultured on the same medium which was optimal for the individual test organism. Test organizations. Staphylococcus aureus 6538, Salmonella cholerasuis 10708, Escherichia coli 11229, S. aureus ATCC 43300 (MRSA) and Vibrio cholerae ATCC 14035, were cultured on Trypticase soy agar (TSA) in the remaining three quadrants of the X dish. Three dishes from each organism, with the appropriate controls, were exposed to the vapor of the side product of the fungus for approximately two, four and six days at room temperature. In order to verify the viability of the test microbe, the fungus was then physically extracted and the control and test dishes were placed in an incubator at 35 ± 1 ٥c for a minimum of three to four days, except Mycobacterium species which have been incubated for approximately an additional month. This was done to check whether the vapor of the by-product had inhibited or killed the test organism and the viability of the organism was assessed. The same protocol was followed for Yersinia pestis and Bacillus anthracis, except that the exposure times were modified to 3 and 5 days and Y. pestis was incubated at 28 ± 1 ٠c and in c٠2 at 5% after exposure to the fungus. Mycobacterium marinum ATCC 927 was cultured on agar 7Η11 (Difco Co) in the three remaining quadrants, using the same protocol indicated above and incubated at 33 ± 1 ° C. The three subsamples in the tests with each organism all behaved in the same way.
For all strains of Mycobacterium tuberculosis, also cultivated on 7Η11, an agar section was extracted from the dish and the fungus Β-23 (on 'PDA) was inserted. Then, the dishes were inoculated with a culture broth. Control μα 38484Β1 dishes, where there was no champigon present, were also incubated. At each designated time interval, a section of agar was removed from the dishes and transferred to a separate, empty dish and placed in an incubator at 35 ± 1 ٠c to determine the viability of the microbe. The dishes were placed in a plastic bag with moistened paper towels to prevent drying.
Pseudomonas aeruginosa 15442 and Burkholderia thailandensis 70038 were both cultured on TSA agar. They were left at room temperature for the optimum growth time for the organism and then moved to an incubator at 35 ± 1 ٥c and observed. It should be noted that all trials using human pathogens have been conducted under stringent biologically safe conditions and approved at the federal level. All tests on human pathogens have been repeated at least twice.

As shown in Table 9, the four acid-resistant bacteria (strains of Mycobacterium tuberculosis) were all killed after an exposure of 2, 4, 7, and 14 days to M. crispans in active growth (culture of 6 10 days). The other bacteria that were killed after at least 2 days of exposure to M. crispans were: Staphylococcus aureus m, Mycobacterium marinum. Yersiniapestis, and Salmonella choleraesuis. The following were minimally affected or not affected at all by exposure to M. crispans: Pseudomonas aeruginosa, Burkholderia thailandensis, Staphylococcus aureus QfÀ١, Escherichia coli, Vibrio choiera and Bacillus anthracis. However, the growth of 5 '. aureus (MRSA) was only a viscous film rather than separate colonies and was affected by M. crispans cov. In addition, there were only a few colonies left in B's dish. anthracis on the display dish, but several colonies grew after the withdrawal of M. crispans and the subsequent incubation. Therefore, it is suspected that the vapor of M. crispans from the by-product is only effective against vegetative cells of B. anthracis, but not against spores. One month after the last observation time (14 days), no growth was observed on the dishes exposed to the fungus and growth was observed on all the control dishes.

Composition with CAA used for the control of plant diseases.
Example 8a The relative ability of the CAAs to inhibit and kill the test organisms was measured. Test solutions were prepared by placing the compounds in vials. The test mixture (20 microliters) was placed in a previously sterilized micro-dish (4 × 6 mm) located in the center of a Petri dish containing PDA. When not in use, the mixture was stored at 0 ٥c. Test organisms (as listed in Table 9), freshly growing and excised on 3 mm agar blocks<sup>3</sup> (at least 3 agar blocks per test mushroom), were placed at a distance of 2 to 3 cm from the (MA
38484Β1 micro-cut and the dish wraps with two layers of Parafilm. The measurements were taken on the mycelial growth from the edge of the agar blocks after a given period of time. However, in the case of Geotrichum candidum they were deposited in a continuous band and were observed to verify the presence of any new visible growth and viability by a new deposition in continuous band from the initial surface of the agar plate which had been inoculated. Appropriate controls were also formed, in which no test solution was placed in the micro-section. Tests on 20 μΐ of the CAA mixture have been carried out at least twice with comparable results.
Example 8b The viability of the test microbes was achieved by aseptically removing the small block of agar and placing it on a PDA dish and observing the growth after 1 to 3 days or by re-depositing Geotrichum candidum in continuous strip on a fiaiche PDA dish. In this way, the viability of the microbes could be assessed. The results shown in Table 1a indicate that the organisms listed below are all inhibited by the composition with particular CAA and in most cases filtered by exposure to it. They include Aspergillus niger, Penicillium sp. on cheese, Cercospora beticola, Verticillum dahaliae, Pythium ultimum, Phytophthorapalmivora, Mycophaeraellafijiensis, Rhizoctonia solani, Aspergillusfumigatus, Geotrichum candidum, Trichoderma viridi, Ganoderma sç., Curvularia ٦١ <؟ and Botrytis alli. خلتغشم, when eWe is applied correctly, a composition with CAA has the ability to control these pathogens. Such results indicate that many other pathogens can be either inhibited or filtered out by this mixture.

Example 8c With regard to the data in Table 11a, the activity profile of the composition with CAA used indicates, in several cases, a different and / or improved antimicrobial effect, compared to M. crispans and to vapors of the volatile by-product thereof.
Example 8d As regards the previous example and using comparable techniques and procedures, the same pathogens were treated with propanoic acid vapors. The results compared are shown in Table 1b, below, the data in Table 11a being reproduced in columns A and B, and the observed effects of propanoic acid, alone, being provided in column c ( inhibition in%). At 20 μΐ, the amount of propanoic acid is comparable to a level of propanoic acid in certain embodiments of the present invention. Propanoic acid is representative of various isolated compounds of the prior art known to have a certain antimicrobial effect. However, as demonstrated by the comparative data in Table 1b, the present compositions provide new and synergistic results superior and beyond those which could be expected independently of a compound isolated from the prior art. outside the context of the present invention. As shown here, although the prior art is at best simply an inhibitor, the compositions of the invention eliminate (i.e., kill) many of the pathogens tested. Similar results can be obtained by comparison with other isolated compounds / compositions of the prior art.

Use of the compositions with CAA name to treat tuberculosis and other human pathogens
EXAMPLE 9a [0128] Four strains resistant to clinical drugs of isolates of
M. tuberculosis (5901867, 50001106, 59501228 and 3081) were exposed to a composition with CAA. For each isolate, 10 µL of the culture was placed in the middle of a 7Η11 agar dish and then spread evenly over the entire surface of the dish with a sterile plastic loop. 0.65 ml microcentrifuge tube sections (micro sections) were cut and autoclaved at 121 ° C for 15 minutes inside an autoclavable tube with a screw lid. Three dishes for each isolate were prepared and 5, 10 or 20 µL of CAA were placed in each of the three micro-sections of the respective dishes.
The dishes were then placed in a zippered plastic bag with a damp paper towel and incubated at 36٥ CIC for approximately 28 days. After about 48 hours, the micro-section was removed and discarded and the dishes were returned to the incubator.
MY

The paper towels were checked frequently and re-wetted to prevent dehydration of the medium. All of the control dishes showed growth. All the pl.ats which had been exposed to 5 and 10 μL of volatile products revealed growth. Only one isolate (50001106) exposed to 20 L of volatile product showed growth. It should be noted that each M. tuberculosis isolate is a strain of this organism that is resistant to clinical drugs. All the experiments were carried out under laboratory biological safety conditions approved by the United States Government.
The control dishes and the dishes exposed to 5 and 10 μL of volatile products were prepared on 04/14/08. The dishes exposed to 20 pL of volatile products were prepared on 04/22/08. All dishes have been checked several times. The final verification was carried out on 05/19/08 and these organisms which did not survive are indicated in Table 12 by "-". Table 12.

The real effects of a composition with CAA of the present invention on another strain of TB are shown in Figure 1: Lethal effect of CAA on a strain (110107) of M. tuberculosis. The left dish is a control dish which has not been treated with 20 microlites of CAA for 48 hours, while the right dish has been treated for 48 hours. The two dishes were then incubated for 28 days at 36 ° C. It is evident from these experiments that the AACs were able to kill 3/4 of the drug resistant isolates of M. tuberculosis. From now on, a prospect is emerging for animal trials then human trials using compositions with CAA in the treatment of tuberculosis.
Example 9b [0131] According to the data of the previous example, more general aspects of the present invention can be demonstrated. Viable cultures and suitable media are prepared using materials and techniques well known to those skilled in the art. For example, exposure to a CAA composition of the present invention (for example, by direct contact with a liquid composition or by vapors thereof) may result in inhibition of the growth or death of coliform bacteria (gram staining

Likewise, such results can also be obtained and demonstrated with various other gram negative and / or gram positive bacteria such as, but without limitation. Bacillus cereus (Gram positive, rod) and Clostridium botulinum (Gram positive.
rod).
Example 10 The IC was calculated for some of the test organisms which were tested against an artificial composition to mimic the volatile side product of M. crispans. (see. Table 1.) With respect to Table 12, all test organisms were 100% inhibited with the use of 15 µL of the artificial mixture and several of them were killed with as little as 10 pL. Verticillium dahliae, Botrytis cinerea and Aspergillusfumigatus were not killed by even the largest volume of the mixture (30 pL), but all three were inhibited at 100 ٥/٠ with 10 or 15 pL of the test mixture. The most sensitive organism was Pythium ultimum, which was killed with 10 pL and inhibited at 100 نره with 2.5 pL, so the cio values do not necessarily reflect the lethal capacity of volatile products like p. ultimum and Botrytis cinerea both have almost identical CIs, but one was killed and the other was not (Table 13).
Table 13. cio of the artificial mixture of the components of the volatile by-product of M. crispans on various plant pathogens. Amounts of the mixture, varying from 1 µL to 30 µL, were added to a sterile plastic well in the center of the test dish and the pathogens were placed around the edge of the plate. Viability was assessed after 48 hours and compared to a control dish with no mixture added but with the sterile well in place. Any organism that showed no growth after this period was considered to be 100% inhibited, while those that showed no growth after 48 hours and no growth after isolation on PDA immediately after the 48 hour evaluation were considered to be dead. The CIO calculation was determined by dividing the amount of the artificial mixture necessary to cause inhibition at 50 ٥/٠ (in pL) by the total air space in the Petri dish (50 mL).

Use of a Composition with CAA for the treatment of refuse to control microbial decomposition.
Example 11
0134] An artificial mixture of items, which would normally be considered garbage, was assembled in two ammunition boxes. These items consisted of grain waste, pieces of flowers, meat waste, newspaper fiber and various other waste. A small beaker containing 0.2 ml of the above-mentioned CAA composition was placed in a crate. In the other case, a beaker was placed without CAA. The two cases were incubated for 10 days at 80 ٥ F. At the end of this period, the funds were opened and examined. It was evident that no decomposition had taken place in the box containing the CAA. In addition, the test case had completely transformed into an enormous amount of decomposition. The use of the composition with CAA for the treatment of garbage is an opportunity to keep the garbage intact and prevent it from decomposing in transit to installations around the world which ferment garbage into products associated with energy such than methane. Figure 4 illustrates that the composition with CAA protected the garbage against microbial decomposition under the conditions of this experiment.
Use of a Composition with CAA for the treatment of cheese to control fungal decomposition
Example 12 A bottle containing 10 ml of the above-mentioned CAA composition was incorporated into or with and / or used to dip a 10 by 10 inch piece of Saran® clear plastic packaging. The plastic packaging was been soaked in the composition with CAA for 6 days, dried by suspension and then used to package the piece of cheese carefully inoculated with a cheese strain Penicillum sp. In another experiment, the piece of cheese was inoculated with the mushroom, then wrapped with ordinary Saran® packaging and then injected with 10 microliters of CAA.

Appropriate controls are shown in the illustration above with Penicillium sp. only, with package treated only, CAA only and control (no treatment). The cheese pieces of the experiment were incubated for 1 week at room temperature and then portions of each cheese item were tasted by laboratory staff. It should be noted that there was no negative effect due to storage in this manner with an alteration in the taste of the cheese compared to a piece of freshly cut and fresh cheese which had been stored in the refrigerator. The piece of cheese completely infested with mushrooms was not eaten. It is obvious from Figure 2 that the use of a composition with CAA under the package or with the treated package caused the almost complete protection of the piece of cheese against the decomposition and colonization of the cheese by Penicillum.؟ p. This was true with the treated packaging and with the injection of 10 microliters of CAA under the cheese wrapped with ordinary Saran.
Use of a composition with CAA for the treatment of pieces of food or plants (for example, plant product) to control fungal decomposition
Example 13a [0136] Several yams were obtained for these experiments. It was thought that microbes contaminating the surface and causing possible decomposition would be abundant enough for the inoculum. Thus, two pieces of yam were placed in a plastic box whose lid was closed in the presence of a small beaker containing 0.2 ml of CAA. The control box contained a beaker without CAA. Then the sealed boxes were kept at room temperature for the day and then examined. It was evident that no surface and deeper contamination had developed on the treated yam pieces, while the control yams developed multiple areas of surface stains and the beginning of decomposition as shown in Figure 3 : the untreated yam is found on the left and the one on the right has been treated with CAA. Note the large area of fungal decomposition on the upper end of the yam on the left.
EXAMPLE 13b As an associated end-use application, a composition with CAA and / or a component thereof can be applied to harvested fruits or vegetables to compensate for the withdrawal of any natural, waxy or protective coating on those -the. For example, harvested squash and similar products, with cut stems, can be sucked with a composition with CAA (for example, with an application by ، MA
38484Β1 spray) to control / inhibit microbial growth, improve marketability and extend shelf life.
Example 14 A composition with synthetic CAA of the present invention, in accordance with the compositions of the kind described in Tables 2 to 7 and 10, supported the comparison with the use of live M. albus for controlling seedling diseases. sugar beet (Beta vulgaris L.) caused by Pythium ultimum, Rhizoctonia solani AG 2-2 and Aphanomyces cochlioides, and root gall nematode, Meloidogyne incognita, on tomatoes (Lycopersicon esculentum). The synthetic composition provided control of seedling loss equal to a starch-based presentation of the live fungus for the three sugar beet pathogens and significantly reduced the number of root galls on tomato roots. Studies of reports with the composition with CAA used revealed that concentrations of 2 μΐ / em<sup>3</sup> and 0.75 μΐ / cm<sup>3</sup> of a soil medium / support component provided good control of rhizoctonia and damping-off of pythium seedlings, respectively, of sugar beet. A concentration of 5 μΐ / crn<sup>3 </sup>sand provided 100% mortality in 24 hours for 44. incognita. In comparison, using in vitro studies, the same biorational ratio provided fewer root galls than a presentation of ground barley infested with M. albus applied to 5 g / l of sand.
Example 15 [0139] Corynebacterium michiganese causes serious loss of tomatoes due to wilting and tissue rot. An authentic culture of this bacteria was spread in continuous strips on culture broth agar and a small cup was placed in the middle of the dish. Into the section were placed 20 microliters of an artificial CAA composition of the present invention prepared in the laboratory. A control dish did not contain a composition with CAA. The dishes were incubated for 24 h, then examined. There was no growth of the bacteria on the flat treated with CAA. (see, Fig. 5.) As such, a CAA composition of the present invention can be used, without limitation, to treat seeds, plants or tomato products. Alternatively, a composition with CAA can be mixed with water as a soil drench solution before transplanting.

As will be understood in the art, using available treatment techniques and equipment, a composition with CAA and / or a component thereof, alone or incorporated into another composition, can be applied (e.g., sprays) on empty shells before further processing, for example into a nutriceutical. Likewise, one or more compositions of the present invention can be applied or incorporated or otherwise used to transform poultry carcasses, meat or an associated cam product, using the apparatuses and techniques known in the art. By extension, a person skilled in the art will understand that the present invention can also be used with other types of animal carcass, meat, processed cam products and all other forms of animal flesh (for example, mammals, birds, fish , snails, clams, crustaceans, seafood and other edible species), as illustrated in one or more of the following examples.
Example 17d [0146] Following on from the previous example, such a composition with CAA can be incorporated into such a processed nutriceutical product (for example, capsules or tablets based on plants or spices) to inhibit bacterial growth. fungal.
Example 17e Although the previous examples illustrate various downstream processing applications, the present invention can be more widely used in the context of egg and poultry production. Without limitation, the compositions with CAA or associated components of the present invention can be introduced into any poultry or egg production installation and / or applied on any equipment or machines
38484Β1 associated with that one. For example, aerial or surface treatment of a henhouse or brooding / laying facility can control, reduce and / or inhibit atmospheric contaminants or deposited on the surface and subsequent microbial growth on that surface.
Example 18 A composition with CAA or one or more components thereof can be incorporated into various other processed food products, including food products having water-related activity that otherwise maintains microbial growth. For example, such a composition or component can be incorporated into humus, peanut butter and other spreads, dips and mixtures. With regard to the peanut culture and processing industries, the compositions and associated components of the present invention can be applied to peanuts before and after breaking the shells, after an initial washing of the peanuts, on a processed product. combination (eg, peanut butter) and / or on packaging equipment and packaging materials.
Example 19 [0149] Likewise, a composition with CAA / a component of the present invention (for example, one or more compositions of Tables 2 to 7 and 10, above, or variations of the kind described herein) can be used in the form of, or incorporated into, various skin care or skin care products, regardless of presentation (e.g., lotion, ointment, cream, etc.).
Example 19a [0150] For example, acne is commonly caused by one or more species of bacteria which invade the follicles of the skin. To demonstrate further use of the present invention, an aqueous presentation of a CAA composition of the present invention comprising substitution with propanoic acid was prepared and used to treat a teenage boy with acne related to 'age. One application every three days for three days significantly reduced, by visual observation, the number and intensity of acne-related lesions.
Example 19b To demonstrate another use of the present invention in the context of a personal care and / or health care product, a CAA composition of the present invention was incorporated (at about 2% by weight) in one, my
38484Β1 representative over-the-counter skin cream preparation. With reference to FIG. 6, a dish of PDA was prepared and incubated for one day with a control cream (without composition or CAA component), at the top left; a control cream contaminated with bacterial cells, top right; a cream "treated" with a composition with CAA, bottom gacuhe; and a cream treated with a bacterial composition, bottom right. As noted, bacterial growth in such a skin cream product has been prevented by incorporating a modest concentration of a CAA composition of the present invention.
Example 20 [0152] Likewise, the present invention can be used in association with a range of hygiene, care and treatment products for the mouth. Without limitation, the following examples demonstrate such use of a composition with CAA comprising substitution with propanoic acid of the kind described above. Alternatively, various other compositions with CAA may be used, in accordance with the compositions of Tables 2 to 7 and 10, above, or variations thereof as described elsewhere herein.
Example 20a For example, to illustrate such an oral care / hygiene product, an oral bath / rinse product was shaped using approximately l٥ / o of such a composition with CAA. Such a product was prepared by incorporating such a composition with CAA into a commercially available over-the-counter oral bath / rinse product. The CAA compositions of the present invention, regardless of concentration or dose level, can also be incorporated into a toothpaste / gel for the teeth or an associated oral, dental, gum or mouth care product.
Example 20b [0154] Lichen planus (LP) is an autoimmune skin disease which appears inside the mouth or on other mucous membranes. As the membranes become unstable, bacteria or fungi can settle in these areas and cause pain, redness, infection, bleeding and swelling of the tissue. In order to reduce the cause of the external involvement of bacteria in this disease, a mouthwash product was prepared which contained a 1% aqueous solution of such a composition with CAA. The patient's mouth was rinsed two to three times daily for, MA
38484Β1 at least 3 to 4 minutes and then emptied. The photos were taken before the treatments were applied and after three weeks of treatment. After 3 weeks, the results revealed an almost total reduction in redness of the gums, accompanied by an almost total reduction in oral and gingival pain as well as a return to an almost normal color of the gums and other mucous membranes. The patient reported almost complete cessation of bleeding pain and better LP relief compared to previous experience.
Example 20c [0155] A 1% solution of the above-mentioned CAA composition in an over-the-counter mouthwash was used to reduce plaque and to treat other problems arising from bacteria associated with oral problems. Daily use, with 3-4 mouthwashes per day for two months, has resulted in little or no buildup of dental plaque. The gums that were originally described as red, swollen and bleeding easily (from notes taken by the dentist) now appeared to be normal in color and no longer bleed when examined with the probe instrument.
Example 20d [0156] To confirm the effectiveness of such a composition with CAA, the oral saliva of the preceding example was placed on one side of a nutritive agar dish, the saliva of a bath of commercially available mouth without CAA was placed on the other side of the same dish and unswashed saliva was placed on another dish. Then the saliva was incubated for two days. By comparison: the non-rinsed saliva had a high bacterial load; the saliva rinsed without the CAA had, as might be expected, a reduced bacterial load; but the CAA-rinsed saliva did not contain any detectable bacteria.
Example 20e In another example, a stomatological surgeon tested a composition with CAA (for example, 1% of a commercially available rinse / bath product) before an oral surgical intervention. The patient placed untreated saliva on an agar dish (nutrient agar), rinsed with the CAA rinse solution and placed this saliva on another agar dish. After two days of incubation, there were no longer any bacterial colonies SUT the dish containing the rinse aid containing CAA, indicating
MY
38484Β1 use before and after oral surgery to treat or inhibit dental and other oral infections.

As the results of Examples 60a and b show, a representative composition of the present invention can be used to effectively inhibit the growth of mold in otherwise predisposed food products.
Example 61 The composition of Examples 60a and b (FF # 2) was tested against representative strains of fungi and bacteria. The composition was placed in a micro-cut in the center of a dish of potato dextrose agar with small inoculum nuts spaced around the central well of the micro-cut to 2 cm. The section contained the amounts of composition which are indicated in Table 16. The dishes were incubated for 24 hours at room temperature and measured. The measurements were carried out on a control dish and the amount of inhibition expressed for the composition is presented as the amount of growth relative to the growth of the control dish (without composition). The percent inhibition results were calculated after a minimum of two measurements for each test organism was performed.

In another test against the same fungi and bacteria, the composition was placed directly in the form of a drop in the center of a dish of potato dextrosed agar with small inoculum nuts spaced around from the center at 2 cm intervals. The dishes were incubated for 24 hours at room temperature and measured. The amount of composition applied is indicated in Table 17. The measurements were carried out on a control dish and the test dishes. The amount of inhibition expressed for the composition is presented as the amount of growth relative to the growth of the control dish.

ND = not determined
The control bacteria grew well and the indication “trace” indicates that a weak growth took place compared to the control.
MA 38484131 The results of this example show that the composition is active in the aqueous phase, since all the organisms, at one or all of the concentrations, were affected during at least 24 hours. At 25 μl, the effect was maximized since most of the organisms were 100% inhibited (Table 16). When the composition was placed directly in the middle of the dish on the surface, the influence of the composition was somewhat reduced, since there was undoubtedly a diffusion in the agar bed. Nevertheless, antimicrobial activity was observed (Table 17). The highest concentration (12.5 µl) affected both the fungi and the test bacteria more than the lower dose (6 µl) on the agar bed, except for Verticillum.
