ANTAGONISTIC ACTIVITY OF BACILLUS SUBTILIS STRAINS, PERSPECTIVE COMPONENTS FOR CREATION OF ROLLED HIGH-MOISTURE CORN PRESERVATIVES
Journal Title: Сільськогосподарська мікробіологія - Year 2017, Vol 26, Issue
Abstract
Antagonistic activity of Bacillus subtilis strains, perspective components for creation of rolled high-moisture corn preservatives was investigated. Investigated B. subtilis strains showed antagonistic activity against pathogenic and conditionally-pathogenic microorganisms. Test-cultures of Escherichia coli and Staphylococcus аureus showed the highest sensibility to the antagonistic B. subtilis strains. B. subtilis strains B6у and В1 showed the best ability to inhibit the growth of pathogenic and conditionally-pathogenic microorganisms. Flora genus composition on rolled high-moisture corn grain was studied. Flora of rolled high-moisture corn grain is presented by the genus Penicillium in 52% of cases, a remainder consists of the genus species Fusarium (13%), Rhisopus (13%), Gliocladium (11%), and Mucor (11%). Above-mentioned 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 the genus species Mucor, Rhisopus, and Penicillium.
