Microbial fuel cells (MFCs) convert electrochemical energy into electrical energy immediately and have a big potential usage for the same time wastewater treatment and energy recovery via electro-active microorganisms. However, MFCs must be efficiently optimized due to its limitations such as high cost and low power production. Finding new materials to increase the cell performance and reduce cost for MFC anodes is mandatory. In the first step of this study, different inoculation sludges such as anaerobic gum industry wastewater, anaerobic brewery wastewater and anaerobic phosphate were tested, and MFC that was set up with anaerobic gum industry wastewater inoculation sludge exhibited the highest performance. In the second step of this study, various wastewaters such as chocolate industry, gum industry and slaughterhouse industry were investigated for anode bacteria sources. Several electrochemical techniques have been employed to elucidate how wastewaters affect the MFCs' performance. Among all the mentioned wastewaters, the best performance was achieved by the MFCs fed with slaughterhouse wastewater; this device produced a maximum power density of 267 mW·m.
微生物燃料电池（MFCs）能立即将电化学能转化为电能，在通过电活性微生物同时进行废水处理和能量回收方面具有巨大的潜在用途。然而，由于MFCs存在高成本和低发电量等局限性，必须对其进行有效优化。寻找新材料以提高电池性能并降低MFC阳极成本是必不可少的。在本研究的第一步中，测试了不同的接种污泥，如厌氧口香糖工业废水、厌氧啤酒厂废水和厌氧磷酸盐，用厌氧口香糖工业废水接种污泥构建的MFC表现出最高性能。在本研究的第二步中，研究了巧克力工业、口香糖工业和屠宰场工业等各种废水作为阳极细菌来源的情况。已采用多种电化学技术来阐明废水如何影响MFCs的性能。在所有提及的废水中，以屠宰场废水为进料的MFCs表现最佳；该装置产生的最大功率密度为267 mW·m 。
