FIELD: biotechnology.
SUBSTANCE: invention relates to the field of biotechnology and can be used to change the activity of bacteria in the reproduction medium. A method for reducing the activity of the Bacillus subtilis bacteria in the reproduction medium, consisting in using water impacted by a high-frequency field with a frequency of 30 to 230 MHz for 90 minutes, at the following composition of media: vegetative medium, g/l: yeast extract - 5, peptone - 15, sodium chloride - 5, water - up to 1 l, pH of 6.8 to 7.0; agarised medium, g/l: agar - agar - 18, yeast extract - 5, peptone - 15, sodium chloride - 5, water - up to 1 l, pH of 6.8 to 7.0.
EFFECT: above method effectively reduces the activity of Bacillus subtilis bacteria in the reproduction medium.
