摘要: BACKGROUND: To investigate the effects of pH on performance and anodic microbes MFCs (microbial fuel cells), double-chamber were fed-batch operated at four different values initial (4, 5, 6, 7) changes in (species appearance) studied. RESULTS: Lower voltage outputs (232–284 mV vs. 311–339 mV) power generation (95–116 mW m−2 182–237 m−2) with faster COD removal obtained under acidic conditions. Simplicispira, Variovorax, Comamonas, Acinetobacter major communities conditions, while Chlorobi, Aquaspirillum, Sphingomonas majority neutral Anodic biofilms cracked reduced ≤5. 4 failed to recover optimal electricity when was readjusted 7. There significant correlations between time-course (anodic cathodic) MFC conditions. CONCLUSIONS: Injured may be reason for decreased ≤4 cause long-term, even irreversible reduction performances.
