[Effect of combination of high-voltage pulses and other physical factors on the intensity of reproduction of Anabaena flos aquae].
It was shown that the influence of high-voltage pulses (intensity of electric field 40-120 kV/cm) on cyanobacteria Anabaena flos aquae can be different and depends on the mode of treatment. It was found that in the range of pulse durations less than 1 microsecond with a pulse repetition rate of up to 500 Hz, and final temperature in the working chamber (60 +/- 1) degree C, a gradual full and irreversible inactivation of cyanobacteria independent of the pulse shape takes place. At the same time, a rapid (but slower than by the action of high-voltage pulses) heating without treatment with high-voltage impulses at the same final temperature leads to an inactivation of 80% of initial cyanobacteria followed by growth of bacteria up to 700% and more.
