摘要

针对微生物污染的工业废水,已经开发并应用了多种净化方法。我们以前报道过高压脉冲放电等离子体与空化有效杀死大肠杆菌细胞。我们试图利用枯草芽孢杆菌、耐辐射球菌和裂糖菌等微生物来扩大这种消毒方法的应用。用放电等离子体处理这些微生物细胞,分析细胞活力、DNA损伤和形态变化,以评价其杀菌效果。有趣的是,耐辐射细菌D. radiodurans对放电等离子体表现出相对较高的敏感性。另一方面,枯草芽孢杆菌和S. pombe均表现出抗性,均表现出产孢能力。处理后细胞DNA损伤程度与细胞活力呈正相关,但大多数处理后细胞未出现形态变化。

Sterilizing Ability of High-Voltage Pulsed Discharge Plasma with Cavitation for Microorganisms Including Radio-Resistant Bacterium in Water.

There are various purification methods have been developed and applied to industrial wastewater with contaminated microorganisms. We previously reported that high-voltage pulsed discharge plasma with cavitation effectively kills Escherichia coli cells. We attempted to expand the application of this disinfection method by using microorganisms such as Bacillus subtilis, Deinococcus radiodurans, and Schizosaccharomyces pombe. These microbial cells were treated with the discharge plasma, and the cell viability, DNA damage, and morphological changes were analyzed to evaluate the bactericidal effect. Interestingly, D. radiodurans, a radio-resistant bacterium showed relatively high sensitivity to the discharge plasma. On the other hand, B. subtilis and S. pombe showed the resistance, showing both sporogenesis. The amount of DNA damage in the treated cells corresponded to the cell viability, but most of the treated cells did not show any morphological changes.
