In forest ecosystems of the southern taiga subzone of the European North-East collected fruit bodies of polypores as promising producers of biologically active compounds and pharmaceuticals. Isolated in mycelial culture 18 strains from eight species and three genera (Trametes spp., Daedaleopsis confragosa and Cerrena unicolor). Studied cultural and microscopic properties of fungi on the solid medium. Revealed differences on growth rate, color, density of filamentous cover and other specific characteristics are of interest for the identification of cultures in laboratory conditions. It is shown that the representatives of polypores can have antibacterial properties, due to the polysaccharides of the cell wall. Different species of the genus Trametes differ in the content of endopolysaccharide in the cell walls of the mycelium (9–49 mg/g). In three-factor experiment showed significant (P≥0,99) influence of medium composition on the accumulation of biomass of mycelium polypores in their growth in deep culture. The results will be used in further studies aimed at the implementation of bioresource potential of forest ecosystems in this region.
