title: Syntrophic propionate oxidation in microbial electrolysis cells
organism: microbial fuel cell bacterium A1
description: Propionate is a key intermediate of anaerobic fermentation. Under methanogenic conditions, propionate oxidation needs syntrophy between propionate fermenting bacteria and H2-utilizing methanogens. Propionate is previously used as an electron donor in microbial fuel cells (MFCs). However preferable pathways for propionate oxidation in MECs and MFCs are unknown. Here we examined the pathways involved for propionate oxidation, reactor performance, electron balances and microbial communities in two-chambered MECs at low (500 mg COD/l) and high (4000 mg COD/l) concentrations.
