摘要

FIELD: chemistry.SUBSTANCE: invention relates to biotechnology and can be used in obtaining nutritional media for growing yeasts. Method includes crushing straw and bran. Crushed straw and bran are mixed in specified ratio. Obtained mixture is hydrolysed with sulphurous acid first at temperature 120-130°C for 60-90 minutes, then at temperature 165-190°C for 25-40 minutes with further distillation of residual amount of sulphur dioxide with its absorption with water. Hydrolysate is separated by centrifugation and mineral salts are added to clarified hydrolysate in accordance with Rieder medium recipe.EFFECT: invention makes it possible to simplify method of obtaining nutritional medium.1 tbl, 6 ex
