Two types of microbial fuel cells (MFCs) were adopted to analyze the effects of exoelectrogens and electron acceptors on the electrogenesis performance of MFCs. One was conventional MFCs inoculated with sewage and using nitrate as electron acceptor (S-MFCs), and the other one was modified MFCs inoculated with anaerobic treated wastewater and using ferricyanide as electron acceptor (A-MFCs). Exoelectrogens and electron acceptors had substantial effects on the acclimation period and the power output period of MFCs. The acclimation period was reduced from 500 h for S-MFCs to 430 h for A-MFCs, and the power output period was prolonged from 100 h for S-MFCs to 350 h for A-MFCs. The modified MFCs increased the removal of COD and the output of voltage by 25% and 300%, respectively. To select appropriate exoelectrogens and electron acceptors were crucial to the improvement of MFCs performance.
采用两种类型的微生物燃料电池（MFC）来分析产电微生物和电子受体对MFC产电性能的影响。一种是接种污水并以硝酸盐作为电子受体的传统MFC（S-MFC），另一种是接种厌氧处理废水并以铁氰化物作为电子受体的改良MFC（A-MFC）。产电微生物和电子受体对MFC的驯化期和功率输出期有显著影响。驯化期从S-MFC的500小时缩短至A-MFC的430小时，功率输出期从S-MFC的100小时延长至A-MFC的350小时。改良后的MFC使化学需氧量（COD）的去除率和电压输出分别提高了25%和300%。选择合适的产电微生物和电子受体对提高MFC性能至关重要。
