FIELD: biotechnologies.
SUBSTANCE: microbial consortium of yeast strains Pichia anomala 9a or Pichia anomala P1 and lactic acid bacillus strain Lactobacillus acidophilus La5 in the ratio of 1:0.8 respectively is created. Solid-phase aerobic cultivation is performed at the temperature of 28-30°C during 36-48 hours. Solid vegetable substrate moistened with liquid component of up to 55-60% of humidity is used for cultivation. Either milk whey, or distillery stillage, or water is used as a liquid component. Convective drying of the obtained polymicrobial product is performed at 38-40°C till residual humidity is not more than 12%. Invention allows obtaining dry polymicrobial product containing increased amount of living bacteria cells of strain Lactobacillus acidophilus La5 - not less than 1*108 CFU/g and living cells of yeast strains Pichia anomala 9a or Pichia anomala P1 - not less than 1*109 CFU/g and increasing product storage life of up to 100 days.
EFFECT: improvement of characteristics.
