摘　　要：采用动态磁场探讨磁场作用下微生物的存活规律.研究结果表明:动态磁场处理后酵母菌大部分死亡;动态磁场对霉菌的影响比对酵母菌更大,约80%的霉菌孢子因为磁场的作用而不能萌发;动态磁场处理细菌因为种类的差异而有所不同,但大部分细菌均失活.动态磁场对微生物的作用造成了细胞结构的破坏,使细胞内的物质(如核酸)泄漏到菌液中.因此,磁场处理技术应用于工业生产中的微生物控制是可能的.This paper investigates the survival law of microorganisms under the action of dynamic magnetic field （DMF）. The research results show that （1） few yeast cells survive under the action of DMF; （2） DMF has a greater effect on mildew than on yeast, and about 80% of mildew spores cannot sprout due to the action of DMF; and （3） most of the bacteria do not survive under the action of DMF although the effect of DMF varies with the species; and （4） under the action of DMF, the cell structure can be damaged, and some cell components of microorganisms, for example, the nucleic acid, can leak from the cell to the broth. It is thus concluded that DMF treatment can be applied to the control of microorganism in industry.
