Aim. The study considers the influence of sensitive test-cultures on antagonistic activity and production antimicrobial factors by indigenous and probiotic microorganisms. Material. The original method has been used. It is based on determination of survival of sensitive test-culture under the action of cultural liquids of antagonist processed by metabolites and peptidoglycan of sensitive culture. Resalts. The important role of sensitive test-culture in manifestation of the antagonism active microorganisms has been proved. Received data have proved that antagonistic bacterial activity is a result of cross-species interaction between active and sensitive cultures. The effectors are antimicrobial factors and their regulators. The ability of bacterial peptidoglycan to regulate the cross-species interaction between prokaryotes has been firstly shown. Conclusion. The article concludes that the investigation has revealed new mechanisms of colonization resistance of biotope. It has opened prospects of development of principal new probiotic, prebiotic, sinbiotic, biologically active additive and functional products on the basis of microbial stimulators of bacterial antagonism
