METHOD OF AEROBIC GROWING MICROORGANISMS BIOMASS PREPARING Russian patent published in 1998 - IPC

FIELD: microbiology, medicinal industry. SUBSTANCE: method involves periodic culturing and additional feeding with medium balanced by the main nutrition components. This additional feeding is carried out under conditions of oxygen limitation at mass-exchange at the range 0.40-1.50 mole $$$ or by its diminish for the last 3 h culturing by 50%. Additional feeding is carried out using the same base as a parent sowing medium by indices of $$$, pH or eH at the ratio C:N:P:Mg = (7.0 $$$ 2.0):(1.2 $$$ 0.5):(0.5 $$$ 0.2): (0.15 $$$ 0.09). EFFECT: improved method of biomass preparing. 2 tbl
