	abstract = {Activated carbon (AC) is a promising electrode material for a bioelectrochemical system (BES) because of its high performance and low cost. Here, AC was flat-pressed with carbon black and polytetrafluoroethylene to fabricate the electrodes. These AC-based electrodes were applied in a single-chamber BES to achieve autotrophic NH4+–N removal under organic carbon-free conditions. In batch experiments, NH4+–N removal could be enhanced by applying voltage to the BES, in which case the NH4+–N removal efficiency gradually increased as the applied voltage increased from 0.1 to 0.25 V. The average NH4+–N removal rate in a BES was 47.8 mg L–1 d–1 in this study, which was comparable with the results of previous studies under similar conditions. Cyclic voltammetry results revealed the presence of several redox-active components on the anode and cathode surfaces, indicating that the AC-based bioanode and biocathode had good electroactivities. Microbial community analysis of 16S rRNA genes based on high-throughput sequencing indicated that the diversity of the microbial community increased after electric power application and that Pseudomonas and Paracoccus could be important for nitrogen-compound removal in the BES.},
