The aim of the research was to create a concept about the signs of self-organization of biofilms and the possibility of directed regulation of their growth; elucidation of mechanisms of biosynthetic and antagonistic properties of a number of groups of microorganisms, which are the basis of directed synthesis of metabolites, which determine the synergistic stimulating and bio-protective effect of the association of streptomyces, microbial antagonists, phytopathogenic bacteria and fungi, entomopathogenic microorganisms; creation of complex polyfunctional environmentally safe microbial preparations with a wide spectrum of action for protection and stimulation of plant growth. In the process of research, modern microbiological, biochemical, physico-chemical, molecular genetic and statistical methods of research, computer processing of data were used. For the first time discovered the differences in growth parameters of S. aureus and S. epidermidis biofilms, intensity of catabolic processes of intact film was investigated, it was shown that dysbiosis obtained by intravaginal introduction of film-forming strains of staphylococci is characterized by a greater stability of microbiota fractures, and the effectiveness of probiotics for the correction of such states is determined. For the first time it was discovered that under conditions of deep cultivation of the metabolites of streptomycetes and the preparation of G3x, an increase in the biomass of the P. ostreatus fungus and E. fetusida vermiculture was observed. The effectiveness of the additive based on vermiculture to the diet of pigs and broiler chickens is shown, which ensures the preservation of offspring and a more intensive increase in the weight of pigs and chickens. For the first time isolated isolates and collection cultures of Streptomyces and Bacillus have been tested for antagonistic activity against different phytopathogenic bacteria and fungi, highly effective associations of microorganisms of different levels of the structural organization - bacteria, fungi and worms - that can be used for the creation of biologically active insecticacaricidal preparations with stimulatory action are selected. for agriculture.
