The influence of electromagnetic radiation of mm- range of low intensity on content of protein and amino acids in biomass of strains Streptomyces canosus CNMN-Ac-02 and Streptomyces massasporeus CNMN-Ac-06 was studied. The obtained results showed that the investigated strains react differently on the exposure to physical factor and it de- pended on the individual physiological characteristics of strain. There was determined an increasing of proteins and amino acids in the biomass of Streptomyces canosus CNMN-Ac-02, while at Streptomyces massasporeus CNMN-Ac- 06 the suppression of synthesis of this substances could be observed, which led to a decreasing accumulation of bio- mass. The optimal exposure time to the electromagnetic radiation of mm – range of low intensity, which increases the amount of biomass and the content of proteins in it, is 5–10 minutes.
