[Antagonistic properties of Lactobacillus plantarum strains, isolated from traditional fermented products of Ukraine].

The antagonistic activity of 109 lactobacillus strains, isolated from traditional fermented products of Ukraine, has been investigated and it has been shown that the significant part of strains show different levels of inhibition of opportunistic and phytopathogenic microorganisms. It has been shown that the antagonistic effect of Lactobacillus plantarum strains on the opportunistic and phytopathogenic microorganisms was dependent on the sources of Lactobacillus strains isolation. L. plantarum strains show a higher level of inhibition against phytopathogenic microorganisms than opportunistic test-strains. Eleven strains of L. plantarum demonstrated antagonistic activity for all used test-strains.
