YEAST MIXTURE FOR HIGH CONCENTRATED ALCOHOL FERMENTATION FROM SUGAR-CONTAINING MATERIAL Russian patent published in 2012 - IPC C12N1/18 C12P7/06 

FIELD: biochemistry.

SUBSTANCE: the yeast mixture used for high concentrated alcohol fermentation from sugar-containing material contains any kind of dry yeast and nutrients necessary for yeast growth. The nutrients includes 40-70 weight parts of dry yeast, 20-40 weight parts of nitrogen source, 5-10 weight parts of phosphorus source, 2.5-5 weight parts of inorganic salt different form the phosphorus-containing and nitrogen-containing inorganic salts, 1-2.5 weight parts of microvitamin and 0.5-1.2 weight parts of penicillin. The yeast is taken from the yeast group containing beer yeast Saccharomyces cerevisiae Hansen from the Saccharomyces cerevisiae species, vine yeast Saccharomyces uvarum Beijerinek. The yeast mixture is received through grinding the nutrients separately, excluding the dry yeast. The dry yeast is mixed with the grinded nutrients with a certain weight ratio, then the mixture is stirred mechanically or manually until it is homogeneous.

EFFECT: increased alcohol fermentation up to 14.5-15.7% in standard raw material, such as sucrose, and reduced sugar residue in fermented mesh down to 0 - 0.1%.
