FIELD: biotechnology.SUBSTANCE: proposed composition comprises a substrate uniformly coated by Lactobacillus casei CNCM MA43/6V bacterium strain biomass, the substrate is represented by Saf-Instant yeast containing 95.5% of dry matter. At that, the biomass of Lactobacillus casei CNCM MA43/6V bacterium strain comprises from 10 to 30% of dry matter based on the total dry matter content of the coated substrate. Method for composition preparation comprises administration of the said substrate into a mixer, through which an ascending stream of heated air passes, substrate coating by spraying a Lactobacillus casei CNCM MA43/6 V bacterium strain biomass suspension, comprising more than 5% of dry bacteria matter, drying by a heated air flow with temperature and flow rate adjusted so that the suspension temperature does not exceed 40°C, to obtain said composition. Also a starter-type ferment activator containing the said composition is proposed. The group of inventions provides a composition with bacteria mortality percentage less than or equal to 0.5 log cfu/g, after one year storage at 20°C in vacuum and/or after one year storage at 4°C in the presence of air. After one year storage in vacuum at 20°C, during acidification test in maltose medium the composition is characterized by pH reduction from 6.5 to 5.7 after 3 hours.EFFECT: reduction of bacteria mortality.16 cl, 2 dwg, 4 tbl, 3 exГруппа изобретений относится к композиции для применения в качестве активатора брожения, способу ее получения и активатору брожения типа стартера. Предложенная композиция содержит равномерно покрытую биомассой штамма бактерии Lactobacillus casei CNCM MA43/6V подложку, представляющую собой дрожжи Saf-Instant с содержанием 95,5% сухого вещества. Причем биомасса штамма бактерии Lactobacillus casei CNCM MA43/6V составляет от 10 до 30% в сухом веществе от общего содержания сухого вещества покрытой подложки. Способ получения композиции предусматривает введение указанной подложки в смеситель, через
