N2 - In this paper, the typical organic component of humic acid (HA) was studied to explore its effect on the co-metabolic biodegradation of Tetrabromobisphenol A (TBBPA) in bioelectrochemical systems (BES). The degradation efficiency, intermediate metabolites and microbial diversity were investigated to demonstrate the impact of HA on the biodegradation of TBBPA in BES-HA-T (Bioelectrochemical system with TBBPA as substrate and HA as a stimulating factor). The highest biodegradation rate (93.2%) for TBBPA were obtained, which illustrated that HA played a positive role in the biodegradation of TBBPA. According to the analysis of the intermediate metabolites, it can be concluded that HA has changed the biodegradation pathway of TBBPA. The analysis of microbial diversity showed that the interaction of microorganisms had great effects on the anaerobic biodegradation of TBBPA, especially Trichococcus and Anaerolineaceae. Meanwhile, the abundance of Desulfobulbus in the BES-HA (Bioelectrochemical system with HA as a stimulating factor) had a positive effect on the improvement of electrochemical system performance.
