摘要

在本研究中，利用柔性电极结构的等离子体发生器建立了大肠杆菌的杀菌性能。以McFarland标准浓度0.50 (1.5×10 CFU/mL)配制菌悬液，并将一定量接种于平板培养基上。等离子体在距离等离子体发生器3cm处放电30s ~ 5min，结果与对照组相比，随着等离子体放电时间的增加，观察到形成的菌落明显减少。

A Study on the Effect of Microbial Sterilization Using Plasma Generator with a Flexible Electrodes Structure

In this study, the sterilization property of E. coli was established using a plasma generator with a flexible electrode structure. The bacterial suspension was prepared based on the McFarland standard 0.50 (1.5×10 CFU/mL) concentration and a specific amount was inoculated on the plate medium. After the plasma was discharged 3 cm away from the plasma generator in the range of 30s to 5 min and the results compared to the control group, the observed colonies that were formed decreased significantly as the plasma discharge time increased.
