Abstract

Abstract: Microbial fuel cell（MFC），one of the novel environmental and energy technologies，is attracting attention of numerous researchers. MFC is a device that utilizes microorganisms to convert chemical energy from organic matter into electrical energy. As a biocatalyst，electricigens play a key role in the development of MFC. Different kinds of electrogenes have different electron transfer mechanism and ability，affect the production performance of MFC directly，then determine the MFC performance and application in engineering practice. Any waste water，sludge，and sediment containing a large amount of microorganisms，try to screening high efficient electrogenes isolated from different environment is expected to promote the further perfect of MFC，so as to accelerate its application in the environment. The latest progress of electricigens in MFCs from several aspects were summarized，including of the development of MFC’s operation，the electricigens species and their electron transfer mechanism，specifically including the screening methods of electricigens，types and the related technology research. Finally，the main research trends of electricigens and the potential application of MFC in the future are also listed，aiming at providing the corresponding theoretical basis and new ideas for the screening and application of electricigens.

Key words: microbial fuel cell, electricigens, electron transfer mechanism
