In this work, the influence of operational parameters such as organic load, pH and temperature on power generation and methane production was studied in a continuous flow air-cathode microbial fuel cell (MFC) seeded with mesophilic anaerobic sludge. Power generation was accompanied by methane production, when fed with either glucose or acetate, however the ratio of methane-to-electricity production strongly depended on operational conditions. At a pH of 7, electricity production exhibited an Andrews-like dependence on carbon source concentration, whereas methane production followed a Monod-like dependence. pH-stat tests showed maximal power output at a pH of 6.3, which coincided with a decreased methane production. Cathode heating to 62 °C resulted in increased electricity generation with an insignificant increase in methane production.
