Characterization of bacterial communities in anode microbial fuel cells fed with glucose, propyl alcohol and methanol

Characterization of bacterial communities in anode microbial fuel cells fed with glucose, propyl... 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Biochemistry and Microbiology Springer Journals

Abstract

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.
