FIELD: biochemistry.
SUBSTANCE: invention relates to biochemistry. Method is proposed for activating spores of Bacillus subtilis bacteria VKPM B-12079 before determining the number of viable cells. Method includes activation of dry spores of Bacillus subtilis VKPM B-12079 with ultrasound for 15–20 seconds at a temperature of 32–34 °C, the frequency of oscillations 35–37 kHz and power 140 W.
EFFECT: invention provides reduced activation time, increased work safety and accuracy of the results.
