چکیده انگلیسی
Air-cathode microbial fuel cells (MFCs), obtained by inoculating with an aerobic activated sludge, were activated over a one month period, at pH 10.0, to obtain alkaline MFCs. The alkaline MFCs produced stable power of 118Â mWÂ mâ2 and a maximum power density of 213Â mWÂ mâ2 at pH 10.0, using glucose as substrate. The performance of the MFCs was enhanced to produce a stable power of 140Â mWÂ mâ2 and a maximum power density of 235Â mWÂ mâ2 by increasing pH to 11.0. This is the highest pH for stably operating MFCs reported in the literature. Power production was found to be suppressed at higher pH (12.0) and lower pH (9.0). Microbial analysis indicated that Firmicutes phylum was largely enriched in the anodic biofilms (88%), within which Eremococcus genus was the dominant group (47%). It is the first time that Eremococcus genus was described in bio-electrochemical systems.
