内容記述
Plasma formation in water is considered to be useful for sterilization because hydroxyl radicals are directly produced; therefore, we proposed an underwater plasma source with a porous membrane which functioned in bubble supply and the formation of gas-liquid interface - discharges. In this study, we examined inactivation of Bacillus subtilis and evaluated the inactivation efficiency in plural reaction areas. The results showed that radicals produced at the gas-liquid interface on a porous membrane made a substantial contribution on decomposition for organic matter such as a methylene blue. However, O3 rising bubbles from a porous membrane were responsible for inactivating Bacillus subtilis having resistance period.
