Abstract

Microbial electrode-respiration process has been proved to significantly enhance the microbial oxidation or microbial reduction of various hazardous organic contaminants in bioelectrochemical systems (BESs). The microbial ecology and physiology of the involved electrode-associated multispecies biofilms are essential for the catalytic function of BESs. In this chapter, we summarize the advances of the electrode-respiring biofilm microbiomes involved in the catalysis of various hazardous organic contaminants at both the cathode and the anode sides. We also highlight the challenges and outlook for the electrode-respiring biofim microbiomes research from the microbial ecology perspective. Understanding the comprehensive information of the electrode-respiring microbiomes, including biofilm structure, composition, dynamics, activity, diversity, potential functional microbes, and interaction, is potentially feasible for regulating and scaling-up the microbial electrode-respiration-based engineering systems as well as the management of bioremediation applications.
