METHOD OF CONTINUOUS YEAST CULTIVATION Russian patent published in 1994 - IPC

Abstract SU 1279236 A1

FIELD: microbiological industry. SUBSTANCE: yeast of species Candida is grown in battery consisting of 3-4 fermenters on synthetic nutrient medium containing ethanol. Biomass is separated from cultural medium from 2-3 fermenters and fed on the head fermenters, where fresh nutrient medium id fed. Flow rate in the head fermenter is 0.35 0.35 h^-1, specific ethanol loading is 0.55 g/h/g biomass. After utilization of 150 g ethanol biomass yield is 81 g, efficiency coefficient is 54% . Metabolic products are not accumulated in the medium. EFFECT: enhanced yield of biomass, decreased accumulation of toxicants. 2 tbl, 1 dwg
