静电场和芒刺静电场对野生型大肠杆菌生长的实验研究

Effects of Electrostatic Field and Prick Electrostatic Field on E.Coli

目的:探讨静电场和芒刺静电场对野生型大肠杆菌生长的影响。方法:大肠杆菌经两种电场处理后,应用分光光度计检测其生长增殖和受抑制情况。结果:(1)在静电场电压值为12kV(板间距离3.5cm)时,刺激生长的作用最为显著,实验组与对照组相比增加了4.05%(p<0.01);而电压值为18kV时,抑制其生长(p<0.5)。(2)在芒刺静电场电压值为4kV(芒刺尖端与下极板间距离2.5cm)时,刺激生长的作用最为显著,实验组与对照组相比增加了12.75%(p<0.005),而电压值为18kV时,则杀菌效果明显[1]。讨论:低强度的静电场和芒刺静电场刺激大肠杆菌的生长,而高强度电场抑制其生长。

To explore the effects of high voltage electrostatic field and high voltage prick electrostatic field on Escherichia colia. Getting the linear equation by counting the number of E.coli and getting the number of E.coli which irradiated in electrostatic field and prick electrostatic field The OD value of Escherichia colia was examed after irradiated in electrostatic fields and we got the results Escherichia colia irradiated in 12 kV of high voltage electrostatic field proliferated most(p<0.01) OD value increased by 4.05% Escherichia colia irradiated in 4 kV of high voltage prick electrostatic field proliferated most(p<0.005) OD value increased by 12.75%. So we can say that some intensity of electrostatic field can increase the proliferation of Escherichia colia.
