The dissemination of antibiotic-resistant microorganisms and antibiotic resistance genes in treatment facilities of Pushchino was studied. The antibiotic resistance plasmids were isolated and characterized as possible vectors for the spread of resistance genes in the environment. The role of catabolic plasmids in the biodegradation of oil hydrocarbons was demonstrated. The horizontal transfer of plasmids was studied under laboratory conditions and in an open environment during the utilization of polycyclic aromatic hydrocarbons. The rhizospheric bacteria of the genus Pseudomonas belonging to the unique PGPR group were studied. The strains produce a wide range of biologically active metabolites, including siderophores, phenazines, 2,4-diacetylphloroglucin, pyoluteorin, pyrrolnitrin, oomycin A, hydrocyanic acid, synthesize phytohormones, including indolyl-3-acetic acid (IAA), and stimulate root formation in plants. Based on one of these strains of P. chlororaphis (formerly P. aureofaciens) BS1393, the biopreparation Pseudobacterin-2 was developed, which is highly effective against a number of plant diseases.
