METHOD OF PREPARING OF YEAST BIOMASS Russian patent published in 1995 - IPC

FIELD: microbiological industry. SUBSTANCE: yeast is grown under aeration conditions on the aqueous nutrient medium containing purified liquid paraffins as a carbon source and mineral sources of nitrogen, phosphorus, potassium, magnesium, trace elements. Sodium sulfite (0.0005-0.001%) and suspension of higher fungi mycelium Polyporus coprinus and others obtained by submerged cultivation were used as stimulating agents for yeast growth. These components were mixed under aeration conditions with trace elements solution (iron, zinc, manganese sulfates) at pH 2-4 and fed for yeast fermentation at concentration 0.005-0.000005% to flow. EFFECT: increased biomass yield, improved quality of product, decreased cost. 3 tbl
