Bacterial communities in anode microbial fuel cells (MFC) obtained from anaerobic digester sludge in a municipal wastewater treatment plant (Nanjing, China) were investigated. Glucose, propyl alcohol and methanol were used as sole carbon source in two-chamber MFC. The results showed that a reproducible cycle of power production can be formed in MFC fed with 3 substrates and glucose-fed MFC had the highest peak power density of 1499 ± 33 mW/m3, followed by methanol- (1264 ± 47 mW/m3) and propyl alcohol-fed MFC (1192 ± 36 mW/m3). Firmicutes, Bacteroidetes, Verrucomicrobia, Proteobacteria, Synergistetes and Armatimonadetes were dominant phyla in 3 MFC. Firmicutes was the most dominant phylum in glucose-fed MFC samples and Bacteroidetes prevailed in methanol- and propyl alcohol-fed MFC. These data indicate that propyl alcohol and methanol along with glucose can be used as substrates of MFC.
