Abstract In order to study the inactivation effects of electrostatic field of electret films on Bacillus subtilis, a plane–plane electrode system was used to simulate the electric field of the electret films and the viability of B. subtilis affected by electrostatic field for different applying durations was investigated. It was found that the survival ratio of B. subtilis can be considerably affected by the field and duration. It was also found that the viability of bacillus decreases with the increase of the duration. In addition, the comparative survival ratio (CSR) of B. subtilis decreases to 35% even during a short duration as the applied field reaches an enough high value of more than 15kV/cm. These indicated that the uniform field inactivated the viability of B. subtilis availability. Based on the inactivation effect of the applied field on the B. subtilis, the effectiveness of charged polypropylene films on the inactivation of B. subtilis was measured and discussed.

静电场对枯草芽孢杆菌的灭活作用

摘要 为了研究驻极体薄膜静电场对枯草芽孢杆菌的灭活作用,采用平面-平面电极系统模拟驻极体薄膜的电场和不同施加时间下静电场对枯草芽孢杆菌活力的影响。被调查。结果表明,枯草芽孢杆菌的成活率受田间和持续时间的影响很大。还发现随着持续时间的增加,芽孢杆菌的生存力下降。此外,随着外加场达到超过 15kV/cm 的足够高的值,即使在很短的持续时间内,枯草芽孢杆菌的比较存活率 (CSR) 也会降低到 35%。这些表明均匀场灭活了枯草芽孢杆菌可用性的生存能力。
