| 摘 要： | 本文以乳酸杆菌、枯草杆菌及酵母菌为研究对象，研究了高压交流电场作用对它们的致死率影响及细胞结构的变化。实验表明：在22．5kv／cm的场强下处理ls能导致乳酸杆菌活菌数降低近6个数量级，通过显微摄影可明显观察到枯草杆菌细胞结构的破裂和酵母细胞的死亡。

| Abstract: | This paper studied the lethal effect on Lactobacillus,Bacillus subtilis and Saccharomyces cerevsiae by high voltage A. C. field. Theequipment was designed and made by ourselves, and its highest electric field up to 30kv/cm. Tests were carried out at different electric field and treatment bine. Experiment results indicate that the viability of Lactobacillus,decreased by 6log. When the treatment time ls is and Eis 22.5kv/cm. By microphotograph, we can. clearly see that the structure of the treated microbe is seriously destroyed. |
