FIELD: biotechnology, veterinary science, microbiology. ^ SUBSTANCE: the strain of bacterium Bacillus subtilis VKM B-2287 is isolated from soil. Bacterial cells are gram-positive with aerobic type of respiratory, don't form capsule but form round spores. The strain hydrolyzes glucose, mannitol and lactose but it doesn't ferment sucrose, inositol, sorbitol and maltose, it doesn't form gas in fermentation process and inhibits the growth of staphylococcus, Escherichia coli, enterobacteria, citrobacteria and aeromonas. The strain is used as industrial one for preparing a preparation named by authors as "Subtilis+". The preparation normalizes function of digestive tract in agricultural animals, poultries and fishes and can be used in treatment and prophylaxis of bacterial infections. Invention can be used for preparing the probiotic preparation. ^ EFFECT: valuable properties of strain and preparation. ^ 1 tbl, 3 ex |
