Abstrakt:

Chemical and bactericidal effects induced by plasma in water upon electro-spraying through DC-driven positive transient spark discharge in air were investigated. Inactivation of Escherichia coli in plasma treated water was determined in dependence on the solution pH (controlled by buffers) and correlated with chemical changes induced in water. Productions of
hydrogen peroxide, nitrites, nitrates, peroxynitrites and pH changes were determined and the extent of oxidative stress induced in bacteria was evaluated by measuring the thiobarbituric acid reactive substances (TBARS). The degree of inactivation and oxidative damage of bacteria increased with increasing acidity of the solution. Acidified nitrites interacting with hydrogen peroxide were determined as the most important bactericidal ROS/RNS agents in water treated by air plasma. A possible role of peroxynitrites, ozone and metal nanoparticles is admitted.
