摘要: 以葡萄糖为唯一碳源,研究了10mA电流下,直流电和交流电对细菌E.dissolvens的电解刺激过程。实验结果表明,10mA电流下,交流电与直流电的施加均能够对细胞的生长和代谢产生促进作用,但在相同的电流强度下,直流电的刺激效果显著强于交流电。通过对电极反应产物的分析,表明可能是电解刺激下产生的氢气,过氧化氢等中间产物所致。Abstract: Behavior of E. dissolvens under the exposure to weak direct current (DC) and alternating current (AC) was investigated by using glucose as the sole carbon source. Water electrolysis was induced in the process of electric field stimulate. When 10mA were applied in the electrode reactions, the implementation of DC led to obvious increase in cell growth and glucose uptake. When AC imposed, the growth of bacteria and degradation of the glucose were lower than the rate of direct current to stimulate indicators were lower than direct current stimulation. Analysis of the reason might be the electrode response led to the solution of the physical and chemical properties caused by changes in the process.
