“…These results suggest that the current generation of EAB is adaptable to changing environmental conditions. 18,19 The relatively low EAB current generation observed in the 2nd and 3rd cycles, compared to the 1st cycle, may be attributed to the presence of residual organic matter from MES construction. However, the similarity in Q values between the 2nd and 3rd cycles confirms the development of mature EAB biofilms in MESs 1-6.…”

“…We constructed a dual-chamber and a single-chamber microbial fuel cell; the sizes and start-up method are shown in Supplementary Text S1. The microbial fuel cell was started using the open-circuit constant potential start-up method that we have previously used (Ren et al 2022). The main composition of the experimentally simulated black water is 1200-1500 mg/L chemical oxygen demand, 90-120 mg/L ammonia nitrogen (NH 4 + -N) and 8-15 mg/L phosphate (PO 4 3− -P).…”

The decline of fossil fuel availability is calling for alternative energy such as electricity produced by degradation of waste in microbial fuel cells. The performance of microbial fuel cells is controlled by the anode because microorganisms grow and attach on the anode. Here, we prepared carbon felt electrodes modified with manganese ore based on the hypothesis that manganese and silicon oxides would improve the cell performance to treat simulated black water. We compared properties of the manganese ore-modified electrodes with properties of classical carbon felt electrodes modified with magnetic ferroferric oxide. We also studied the removal of the chemical oxygen demand and the enrichment in ammonia nitrogen. Results show that the maximum voltage of the manganese ore-modified carbon felt electrode is 1.7 times higher than that of the magnetic ferroferric oxide-modified carbon felt electrode. The start-up time to reach the maximum voltage is reduced by 68%. The removal of chemical oxygen demand reached 91.2%. Up to 68.0% of ammonia nitrogen can be enriched at the cathode, imply-ing that ammonia nitrogen can be highly reduced in the effluent. Overall, the manganese ore-modified carbon felt electrode showed excellent redox performance, excellent corrosion resistance and low electron transfer resistance.
