Power densities and microbial communities of brewery wastewater-fed microbial fuel cells according to the initial substrates

Single-chamber microbial fuel cells (MFCs) acclimated with glucose, butyrate, propionate, acetate, and a mixture of the four were operated with brewery wastewater (BWW) under a fed-batch mode. Glucose-fed MFC (GW-MFC) showed the highest maximum power density (PD max ) of 1,519 mW/m 2 , followed in o...

Description
Summary:Single-chamber microbial fuel cells (MFCs) acclimated with glucose, butyrate, propionate, acetate, and a mixture of the four were operated with brewery wastewater (BWW) under a fed-batch mode. Glucose-fed MFC (GW-MFC) showed the highest maximum power density (PD max ) of 1,519 mW/m 2 , followed in order by acetate-fed MFC (AW-MFC), mixed substrates-fed MFC (MW-MFC), butyrate-fed MFC (BW-MFC), and propionate-fed MFC (PW-MFC). After changing to BWW, power production was decreased for all MFCs. MFC acclimated with glucose showed the highest PD max of 890 ± 12 mW/m 2 , followed in order by MW-MFC, AW-MFC, BW-MFC, and PW-MFC. The PD max in BWW-MFC, which was acclimated and operated with BWW, of 552 mW/m 2 was less than that of GW-MFC and MW-MFC but more than that of AW-MFC, BW-MFC, and PW-MFC. MFCs with fermentable substrates were less affected by the BWW. Gammaproteobacteria, including Pseudomonas sp., Acinetobacter sp. and Xanthomonas axonopodis, were found in all MFCs with pure substrates and Rubrivivax benzoatilyticus , thiobacillus sp. and Denitratisoma oestradiolicum belonging to Betaproteobacteria were newly detected in all MFCs when the substrate was changed to BWW.
