FIELD: microbiological industry. SUBSTANCE: method involves microorganisms culturing under condition of stirring and aeration on nutrient medium containing nitrogen and carbon source and essential minerals. Ortho-chlorophenoxyacetic acid tris-(2-hydroxyethyl)-ammonium salt is used as growth stimulating agent. Additionally, growth stimulating agent gibbersib at concentration 1•10-12 - 1•10-8 wt.-% is added to the fermentation medium. Addition of the indicated above stimulating agents ensures to increase biomass yield by 8-25% and provides synergistic effect with respect to biomass production. EFFECT: improved method of producing, increased yield.
