Both generate cold non-equilibrium plasma. Electro-spraying of the treated water through the needle electrode resulted in fast bio-decontamination. Experiments providing separation of various biocidal plasma agents, the emission spectra, oxidation stress measurements in the cell membranes, and chemical changes induced in the treated water helped better understanding of the plasma agents responsible for microbial inactivation. Radicals and reactive oxygen species seem to be dominant biocidal agents, although understandin Workplace Institute of Plasma Physics Contact Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Year of Publishing 2012
