Disinfection using ozone microbubbles to inactivate phytopathogens

为了建立一种用臭氧微泡(O_3MB)对水培培养液进行消毒的方法，检测了O_3MB对植物根部病原菌的消毒活性。与臭氧微泡相比，O_3MB具有更高的溶解度，在水中停留的时间更长，对两种植物病原体都具有极高的杀菌活性。此外，随着溶解臭氧初始浓度的增加，经O_3MB处理的水对这两种植物病原菌的杀菌活性和耐久性都有所提高。因此，O_3MB有可能作为一种新型的植物病原菌消毒剂应用于水培中。

To establish a method for disinfecting hydroponic culture solutions using ozone microbubbles(O_3MB), we examined the disinfectant activity of O_3MB against phytopathogens in infected plant roots. O_3MB had a higher solubility and remained in the water for a longer period than ozone millibubbles, resulting in extremely high disinfecting activity against both phytopathogens. Furthermore, disinfectant activity and durability of O_3MB-treated water against both phytopathogens increased with an increase in the initial concentration of dissolved ozone. Therefore, these results suggest that O_3MB may be suitable for use as a new disinfectant against phytopathogens in hydroponic culture solutions.
