Abstrakt: The results are given of investigation of the inactivation of microbiological cultures in moist and dry states by low-temperature plasma of a low-power diffuse pulse-periodic discharge (up to 5 W) initiated in the air at a pressure of tens of torr and with an interelectrode gap of up to 10 cm. Escherichia coli and Staphylococcus epidermidis, inoculated onto test samples in an amount of ∼108, were used as reference cultures. It is found that a complete sterility of moist and dry test samples is attained after 15 minutes of treatment at an average discharge power of 0.3–0.4 W and 3–4 W, respectively. The inference is drawn that charged particles play a determining part in the bactericidal effect of the discharge. [ABSTRACT FROM AUTHOR]
