FIELD: microbiological industry. SUBSTANCE: desired strain is prepared by irradiation of culture. The process is carried out with the help of electron having power 100-250 keV, current density is 6·10-5-5,0 A/cm2, duration of pulse is 0,5-10-7 s, interval being 1.5-6 s. Irradiation dose is 10-3-20 Mrad. EFFECT: increases activity of producer.
