FIELD: food products; alcoholic beverages.
SUBSTANCE: method of obtaining biocatalyst for alcoholic fermentation comprises increasing biomass of yeast Saccharomyces cerevisiae and immobilising it by including it in helium matrix by way of mixing with gelling material solution with its subsequent curing by ions Ca++. Gelling material is represented by mixture of exopolysaccharide with molecular weight 1.5·105-2.5·105 Da, derived from Paracoccus denitrificans All-Russian collection of industrial microorganisms B-8617 bacteria strain and sodium alginate in mass ratio 0.1-0.9:3.5.-4.5.
EFFECT: obtaining highly active biocatalyst with long work period for alcoholic fermentation basing on free yeast cells for industrial production of ethanol as chemical while using it as fuel.
