Antagonistic activity of Bacillus subtilis strains, perspective components for creation of rolled highmoisture corn preservatives was investigated. Investigated B. subtilis strains showed antagonistic activityagainst pathogenic and conditionally-pathogenic microorganisms. Test-cultures of Escherichia coli andStaphylococcus аureus showed the highest sensibility to the antagonistic B. subtilis strains. B. subtilisstrains B6у and В1 showed the best ability to inhibit the growth of pathogenic and conditionallypathogenic microorganisms.Flora genus composition on rolled high-moisture corn grain was studied. Flora of rolled highmoisture corn grain is presented by the genus Penicillium in 52% of cases, a remainder consists of thegenus species Fusarium (13%), Rhisopus (13%), Gliocladium (11%), and Mucor (11%). Abovementioned micromycetes showed high sensibility towards investigated B. subtilis strains. Antagonistic B.subtilis strains showed the highest rate of antifungal activity against test-cultures of micromycetes of thegenus species Mucor, Rhisopus, and Penicillium.
