FIELD: chemistry.SUBSTANCE: method of producing microorganism growth stimulators involves growing Fusarium sambucinum MKF-2001-3 or Fusarium sambucinum BKM F-3051D yeast strains on a medium which contains a source of carbon 3-4%, nitrogen 0.2-0.3%, phosphorus - 0.2-0.3% and trace elements - 0.07-0.08% in sterile conditions at temperature of 26-30°C with stirring and aeration for 40-48 hours. The obtained yeast suspension or culture fluid is titrated with hydrochloric acid to pH=4.0-4.5, heated for 1.0-1.5 hours to 115°C, held for 2 hours, cooled for 1.0-1.5 hours to room temperature.EFFECT: method provides intense growth of microorganisms by stimulating biological activity of their growth factors which results in more complete recycling of the substrate and increases output of the end product.10 ex |
