METHOD FOR PRODUCTION OF Saccharomyces cerevisiae YEAST GROWTH STIMULANT Russian patent published in 2013 - IPC C12N1/18 C12R1/85

Abstract RU 2483105 C1

FIELD: biotechnologies.

SUBSTANCE: method provides for degreasing of buckwheat straw with 100% acetone. The degreased straw is extracted in 5 l of 70% ethyl alcohol in boiling water bath for 1 hour. The extracted raw materials are separated by filtration to produce alcohol extract. The produced alcohol extract of the stimulant is concentrated under vacuum, cleaned from admixtures with ethyl acetate and dried to prepare target product.

EFFECT: invention makes it possible to increase yield of yeast biomass.
