Study of changes in the physiological state of cyanobacteria caused by weak ultrasonic treatment

Resumo

The effect of weak ultrasonic radiation with a frequency of 60 kHz on photosynthetic activity of living cells of cyanobacteria was studied using microspectrometric methods for the first time. An inhibitory effect on the physiological state of separate cells and the whole culture was demonstrated. A high efficiency of the method developed by the authors of this article for determination of the viability of cyanobacterial cultures in vivo for the purpose of operational environmental monitoring of the results of weak external influences was demonstrated.
