The microbicidal effect of low-temperature plasma generated by corona discharge: Comparison of various microorganisms on an agar surface or in aqueous suspension

Abstract

The sensitivity of various microbes to the low temperature plasma generated by negative corona discharge in the point-to-plane mode was tested. On the surface of agar semisolid cultivation media, the inhibition zones in microbial cultures were obtained and their areas were compared as a measure of microbicidal effect for nine microbial species including bacterial spores and a yeast species.
