Antimicrobial action of a discharge with a liquid cathode on the electrode liquid

Abstract

The antimicrobial influence of a discharge with a liquid cathode on an electrode liquid at atmo spheric pressure was studied. The degree of the antimicrobial action of the discharge was shown to depend on the treatment regime and on the species of investigated microorganism test cultures. Gram negative bacteria Pseudomonas fluorescens show the most prominent sensitivity to the treatment. Yeastlike fungi Candida albi cans and gram positive bacteria Bacillus subtilis are more resistant toward the action of the discharge. Increas ing the duration of the treatment and raising the current from 60 to 150 mA leads to an increase in the inhib iting action on cells of P. fluorescens and C. albicans.
