FIELD: biotechnology, in particular propionic acid bacterium-enriched food production.
SUBSTANCE: claimed method includes introducing of propionic acid bacterium culture strain Propionibacterium shermanii activated with β-galactosidase in amount of 3-5 mass % in nutrient medium based on milky whey with addition of cobalt chloride in amount of 0.003 g/l. Then cells are grown, bacterial mass is separated from cultural medium, blended with protective medium, poured, frozen and dried.
EFFECT: bacteria of increased biochemical activity, bacterial concentrate for milk and food fermentation without addition of growth substances.
