Abstract

Experimental results on peculiarities of bactericidal effect of atmospheric plasma components and narrowband ultraviolet (UV) radiation of barner discharge XeBr- and KrBr-excilamps on the cultures Escherichia coli and Staphylococcus aureus are presented. Combination of such plasma components as UV radiation at 190 < λ < 220 nm and electroneutral particles is shown to possess the best sterilizing action. A KrBr-excilamp is shown to possess the unique spectrum, which corresponds to maximum of DNA inactivation section of microorganisms.
