臭氧对真菌杀灭作用的初步研究

以根霉 ,黑曲霉 ,青霉 ,酵母菌等为研究对象 ,测定了放电时间与致死率的曲线关系 ,并观察了与空白对照后其菌落形态的变化。实验结果表明 ,随着放电时间的增长 ,致死率明显升高 ,且能够达到完全杀菌。

STUDY ON THE STERILIZATION EFFECTS OF FUNGI BY THE TREATMENT OF OZONE

In this paper, the lethal effect on Rhizopus, Aspergillus niger, Penicillium by ozone was studied. The mortality rate against the time of the treatment of ozone and the variation of ozone concentration was measured. The changes of cell form were also observed. The Experiment results indicate that fungi could be destroyed completely by ozone and the mortality rate obviously increase with the prolonging of treatment time. When ozone was absorbed by KI,the mortality rate declines.
