概要 The bactericidal effect of gas plasma on vegetative bacteria, including Escherichia colo K12, Escherichia coloO157:H7, Sal,pnella typhimurium or Pseudomonas aeryginosa, in 0.9% (w/v) NaCl was investig...ated under atmospheric pressure. Circumambient air, which had 40% relative humidity (r.h.), was introduced into the plasma-generating unit at 7l/min, and was excited by applysing ratio frequency discharge (20kHz) to a conductive electrode in the unit. This caused the circumambient air to form atmospheric gas plasma (AGP). By exposing each cell suspension surface to the AGP, 10[7] CFU/ml of viable reduction was archeived within 15min in all strains tested. Those survival curves showed a two-step process, a slow process, a slow process followed by a much faster one. The bactericidal effects was not attributed to ozone. The AGP with circumambient air apparently increased the electrical conductivity in deionized water. It as concluded that ions from the AGP was responaible for the bactericidal effect.続きを見る
