Abstract
Identification of heterotrophic microorganisms from the biofilms formed on the plates subsurface rock developed representatives of the genera Pseudomonas spp., Serratia spp., Kocuria sp., Bacillus spp. and Paenibacillus spp. It was demonstrated that some strains able to inhibit the growth of natural bacteria of the genus Bacillus spp., as well a number of opportunistic pathogenic microorganisms that can cause various diseases in humans. Of particular interest are bacteria of the genus Paenibacillus, which possess a broad spectrum of antimicrobial activity, as compared to other strains antagonists. It is obvious that their study is of practical interest in biotechnology.
