FIELD: food industry.
SUBSTANCE: method includes preparation of yeast water suspension, addition of potassium alginate into it. The potassium alginate is preliminary kept in water solution of ethyl alcohol with concentration of 50 - 85 vol. %. Exopolysaccharide with molecular mass of 0.5×106-2×107 Da, obtained from Paracoccus denitrificans VKPM B-8617 bacteria strain is added into the obtained mixture with the following obtaining of pH mixture values till 4.2-6.5. The mass ratio of the exopolysaccharide is: alginate is 0.1-0.9:3.5-4.5. Obtained technological solution is treated by coupling solution of calcium chloride.
EFFECT: increase of life time of biocatalyst work with preservation of high activity.
