Antimicrobial Effect of Plasma-Activated Tap Water on Staphylococcus aureus, Escherichia coli, and Candida albicans

In this study, the potential antimicrobial activity of plasma-activated tap water (PAW) was evaluated against Staphylococcus aureus, Escherichia coli, and Candida albicans. For this, PAW prepared in a gliding arc plasma system using two treatment conditions: stagnant stirring by magnetic stirrer, called moving water. Subsequently, their oxidation-reduction (ORP), pH, electrical conductivity (?), total dissolved solids (TDS) were monitored different areas sample divided according to depth beaker. It observed that obtained dynamic conditions showed more uniform acidity among with pH 3.53 ORP 215 mV. Finally, standardized suspensions aureus (ATCC 6538), coli 10799), albicans (SC 5314) treated PAW, reduction viable cells determined effect. Our results indicate water, activated arc, is an excellent inactivation agent case coli. On other hand, no significant achieved for
