Pentachlorophenol (PCP) was more rapidly degraded in acetate and glucose-fed microbial fuel cells (MFCs) than in open circuit controls, with removal rates of 0.12 ± 0.01 mg/Lh (14.8 ± 1.0 mg/g-VSS-h) in acetate-fed, and 0.08 ± 0.01 mg/L h (6.9 ± 0.8 mg/g-VSS-h) in glucose-fed MFCs, at an initial PCP concentration of 15 mg/L. A PCP of 15 mg/L had no effect on power generation from acetate but power production was decreased with glucose. Coulombic balances indicate the predominant product was electricity (16.1 ± 0.3%) in PCP-acetate MFCs, and lactate (19.8 ± 3.3%) in PCP-glucose MFCs. Current generation accelerated the removal of PCP and co-substrates, as well as the degradation products in both PCP-acetate and PCP-glucose reactors. While 2,3,4,5-tetrachlorophenol was present in both reactors, tetrachlorohydroquinone was only found in PCP-acetate MFCs. These results demonstrate PCP degradation and power production were affected by current generation and the type of electron donor provided.
五氯酚（PCP）在乙酸盐和葡萄糖喂养的微生物燃料电池（MFC）中的降解速度比开路对照快，在初始 PCP 浓度为 15mg/L 时，乙酸盐喂养的 MFC 中的去除率为 0.12±0.01mg/L h（14.8±1.0mg/g-VSS-h），而葡萄糖喂养的 MFC 中的去除率为 0.08±0.01mg/L h（6.9±0.8mg/g-VSS-h）。15mg/L 的 PCP 对乙酸盐的发电没有影响，但葡萄糖会降低发电。库仑平衡表明，PCP-乙酸盐 MFC 中的主要产物是电（16.1±0.3%），PCP-葡萄糖 MFC 中的主要产物是乳酸盐（19.8±3.3%）。电流的产生加速了 PCP 和共底物的去除，以及在 PCP-乙酸盐和 PCP-葡萄糖反应器中降解产物的去除。虽然两种反应器中都存在 2,3,4,5-四氯酚，但四氯对苯二酚仅在 PCP-乙酸盐 MFC 中被发现。这些结果表明，PCP 的降解和发电受到电流产生和提供的电子供体类型的影响。
