Abstract

In this study, the sterilization property of E. coli was established using a plasma generator with a flexible electrode structure. The bacterial suspension was prepared based on the McFarland standard 0.50 (1.5×108 CFU/mL) concentration and a specific amount was inoculated on the plate medium. After the plasma was discharged 3 cm away from the plasma generator in the range of 30s to 5 min and the results compared to the control group, the observed colonies that were formed decreased significantly as the plasma discharge time increased.
