Abstract: Bio-electrochemical system (BES) was an emerging biomass-energy recovery technology based on electricigens electron transfer (EET), which was applied to recover electric energy (e.g. microbial fuel cell, MFC) and resources (such as hydrogen and methane) and to enhance the removal of heavy metals and refractory organic pollutants (e.g. POPs). The process of electron transfer to the electrode was identified as the key process in such a BES system. In this paper, the recent research achievements about EET both at home and abroad were analyzed and summarized, and the electricigen diversity, the electron transfer pathways and study methods were systematically presented. Finally, the direction of EET research was pointed out.
