METHOD FOR ENHANCEMENT OF MICROORGANISM PRODUCTIVITY Russian patent published in 2003 - IPC

FIELD: microbiology. SUBSTANCE: invention relates to methods for enhancement of productivity of microorganisms used in food and pharmaceutical industries. Suspension of microorganisms is subjected for irradiation in spectral intervals of the nearest IR and visible range corresponding to bands absorption of molecular oxygen dissolved in the suspension. Irradiation dose is calculated by the formula: D = D_o×β/f(λ) where D_o = D(λ_o) means optimal dose of irradiation of suspension in the center λ_o of taken absorption band of O₂; β means probability of photons adsorption in taken volume of the suspension; f(λ) means contour of absorption band of dissolved molecular oxygen being f(λ_o) = 1. Method allows to enhance productivity of microorganisms of different species. EFFECT: enhanced productivity of microorganisms. 3 cl, 2 tbl
