FIELD: microbiology, pharmacy.
SUBSTANCE: invention relates to a method for isolating biomass of microorganisms from cultural fluid and can be used in manufacturing preparative formulations of biopreparations. Method involves addition of high-molecular reagent "Givpan" as a flocculant representing a product of hydrolysis of polyacrylonitrile copolymer of acrylonitrile with methacrylate. "Givpan" is added in the amount 0.1-0.8 wt.-% of the cultural fluid volume. Applying the proposed method allows retaining activity of microorganisms to be isolated that are antagonists of fungal phytopathogens and amount of viable cells.
EFFECT: improved isolating method.
