Method of control of microorganism growth process
Abstract
A management method for operating aqueous microorganism growth processes is provided which can maintain viable growth conditions for many types of microorganisms that have not so far been easily reproduced in commercially valuable quantities. The primary control parameters are the rate of turbulence in the aqueous growth medium and the scale of the apparatus relative to the scale of the turbulent vortices in vessels partially filled with the aqueous medium directly affect conditions required for optimal growth: light exposure, food supply, sedimentation rate, bulk temperature. , gas exchange rate and cell integrity. These control elements can be given a form expressed as the Reynolds number (Nj-g) and controlled dimensions of the apparatus (L ^) to the scales of turbulent swirls to define dissipation X, ^ as Lj ^ / L. Alternatively, these may be perceived to show that the delivery of food to the microorganism mass is dependent on the dissipation rate E of the fluid, which allows quantification of the definition of L 2. The widest ranges generally useful in this invention are Nj-e = 2,000 - 10,000, preferably 4,000 - 250,000, the apparatus scale relative to the swirl scale such that the fluid level in the reaction chamber relative to the swirl scale is 0.1 - 1 chamber volume unit , preferably 0.1 - 0.8: 1, and turbulent energy dissipation rate E between 10 "- 10 and 10 W / kg. The invention is particularly useful for controlling growth processes in which the microorganisms are single-celled algae, phytoplankton, vascular plant tissue, macroalgae tissue, and the like.
