Abstract

Microbial fuel cell is a bio-electrochemical system that drives a current by using bacteria and mimicking bacterial interactions found in nature. The electricigens and its activity have important influence on the power generation capacity and organic matter degradation ability of MFC system. The common types of electricigens and their application situation in microbial fuel cell are summarized in this paper, the basic characteristics and electron transfer mechanism of some major microorganisms are described, so as to provide some ideas for electricigens’ selection, transformation and optimization of a variety of strains to improve the power generation capacity and organic matter degradation ability of MFC system.

Keywords: Degradation ability, Electricigens, Microbial fuel cell, Power generation capacity, Wastewater treatment.
