The subject of the invention is a process for the production of amides, which consists in the hydration of nitrile and its transformation into an appropriate amide as a result of the action of nitrite hydrate produced by small-scale companies. Exactly, it is a method of biological amide sparking, distinguished by the microorganism used and the method of producing nitrile hydrate.
Lower allpharic acid, such as acrylamide, is prepared by hydrating a nitrile, such as acrylorntrile, with a number of methods of hydration proposed by the action of enzymes such as nitrilase or ntryloo hydrate produced by microorganisms / see e.g. Japanese Patent Application Publication No. 21519/87, US Patent No. 4,001 081, not issued, Japanese Patent Application Publication No. 162193/86 1 91189/87, European Patent Applications No. 0 188 316 1 0 204 555 and Japanese Patent Applications No. 17918/81 1 37951/84, as well as US Patent Nos. 4,248,998 and 4,637,982. Such biological production methods for amide have been used on an industrial scale and have been highlighted as preferred methods for producing acrylamide.
To date, a number of microorganisms have been proposed for biological production of amides. However, it has been found that, although these microorganisms are effective in the hydration of lower aliphatic nitriles, they are not always effective in the hydration of aromatic nitriles. For example, in the production of nicotinamide by hydration of 3-cyanopyridine, insufficient performance is obtained from an industrial point of view.
There is a known way of cultivating microorganisms in the presence of iron or mannan ions. This method is also used in the biological process. For example, the culture of Rhodococcus microorganisms in the presence of iron ions is disclosed in Unexamined Published Japanese Patent Applications Nos. 162193/86 and 91189/87.
As a result of the research, it was found that the enzyme nitrile hydration, or filamentous hydratase, found in bacteria of the genus PtJudoeonθ, contains Fe ion in the center of activity, and in this connection the presence of Iron Ions in the culture environment is of decisive importance for breeding of micro-organisms. For the sake of this, in the case of microorganisms of the genus RhodrcrcJut, the known examples described above also assume that Iron ions in the microbial culture environment are of decisive importance for the production of the nitrile hydrate enzyme.
The invention is based on the discovery that a specific strain of the genus, i.e. strains 3-1 of the species R ^ <^ <^ <^ c ^ f ^ rrut does not produce hydrate, mitigates in a culture environment containing iron ion and that this strain produces nitrate hydrate in a culture medium containing Jon kobaHu, and also that the nitrite hydratase produced in this way can be used in reaction with an aromatic nitrite as a substrate, which is then converted to an amide. In this connection, the method for producing the amide according to the invention is a method for producing the amide by biological means in which the nitrile breaks away from the corresponding ammdu as a result of the action of the hydrated enzyme produced by the hydronase, characterized in that the hydrated enzyme obtains in the cultivation of RhodococJut rhodochrous microorganisms in the presence of tobium and kobaHu ions.
In accordance with the invention, it turned out that Although nitrite hydratase has zero activity in a culture medium containing iron ion, this activity is increased by a culture environment containing ion kobaHu. Unexpectedly, it turned out that the development of nitrate hydrate in these particular microorganisms strongly depends on the type of mmeon ion in the culture environment.
Hydration of aromatic nitrile can also be successfully carried out by the method of the invention. The process according to the invention is of practical importance because of the importance of the hyd ^ aacc product! 3-Janrplridine, nicotinic acid - a drug for the synthesis of vitamins, or a product of hyda- aa ^ and cyanopyrazine, a pyrazinamide useful as an anti-tuberculosis drug.
1. General concept of the biological method for amide production.
The invention relates to a method for nitrile hydrates to convert it into the corresponding amide by the action of ytroyro hydrate produced in durbnutrition, the process essentially involving culturing of durrobes, induction of nitrite hydration and trihydration so that the nitrite nitrate hydrate produced in this way acts on the nitrite hydrate.
These stages are known as Unit operations and are used in an appropriate form in the process of the invention. The term nitrate hydratase is obtained in microbial culture in the presence of cobalt ion and obviously also includes induction of nitrile hydrate.
The determination of the nitrile hydacylation method to convert it to the appropriate amine as a result of the action of the nitrile hydrate produced by microorganisms includes any secondary dilutions or post-drug variants that the hydratase acts on nitrile.
□ One of these solutions includes a method of collecting the enzyme produced by durbπoustΓrje and using this enzyme as an enzymatic preparation. It is understood that such a method of using nitrile hydrate, in which the enzyme is used in the form of an enzyme preparation, is a category of the biological production method of the invention.

As a result of testing other biochemical properties it was found that it is a Rhodococcus Rhodoccwoue bacterium.
OrolnoketrkJa I am inclined to him in Thai. Therefore, it goes without saying that even a twaltttated mutant of a strain such as strain 0-1 can be used in the process of the present invention, as long as the breeding product produces nitrite hydride in the presence of tobatite ion.
Nitriles, which can be used As substrates for nitroyl hydrate produced by the drkbokutrokone described above, are aromatic and alpha-matric or dihydrate, in particular monohydrate.
The nitriles that are best suited for use in the process of the invention are aromatic nitriles, especially those that contain 4-10 carbon atoms with too much aromatic ring. A number of typical examples of aromatic nitriles include compounds represented by general formulas 1-6, including the ulcer of formula 1, preferably 4-, 3- or 2-yyJ8nzpyridia and the compound for sea 2, wherein R ^ and R ^ are hydrogen, CH groups ^, OH, OCH ^, Cl, I,

Another group of trillins useful in the process of the invention are preferably alitatic nitriles, Even more preferably mono- or di-methyl containing 2-6 carbon atoms, most preferably moo-nitriles. Due to the usefulness of the produced amides, a typical example of a nitrile is acrylonmryl, which is transformed into an amide with good hydration. It goes without saying that amides zdpowoadaJąya nlttykmm are compounds obtained as a result of the transformation of the CN group in nitriles into the CONHg group. In the case of two times the corresponding amides are obtained by converting at least one CIJ group into a CONHH group.

One of these solutions involves the production of amide in a culture medium when the substrate nitrile is present in the culture of microorganisms.
Another solution that suppresses nitrate hydrate on the substrate is that in order to carry out the hydraacc reaction, a non-fat substrate is added to the culture medium in which nitrile hydrate has accumulated. A variation of this solution is to use the bodGow ^ environment in which com ^! microbes have been destroyed as a breeding environment in which iltryWowd's hydratase<sup>,</sup>.
Another solution ensuring the action of nltryWoyrj hydrate on the substrate is to isolate the cells in which the nitroyoy hydratase has accumulated from the culture environment, preferably by introducing cells on the appropriate carrier or immobilizing them, and then bringing them into contact with the substrate. This method, and in particular the preferred solution, according to which immobilized cells are used. It is considered suitable for industrial use just as or more than other solutions described in p ^ ^ i ^. This method of application of immobilized cells is widely used, which is also true for the selection of the type of carrier for the method of immobilizing microorganisms as carriers, such as the use of immobilized microorganisms in a so-called biological reactor.
