Abstract :
This paper investigates the sterilization effects of a low-temperature cyclonic atmospheric-pressure plasma. Bacillus subtilis was exposed to the cyclonic atmospheric-pressure plasma, and the degradation of the bacterial cell was thoroughly examined with scanning electron microscopy. It was found that cyclonic atmospheric-pressure plasma is effective in the destruction of the B. subtilis cells.
