The bioelectrocatalysis in microbial fuel cells (MFCs) relies on both electrochemistry and metabolism of microbes. We discovered that under MFC microaerobic condition, an arcA knockout mutant Escherichia coli (arcA–) shows enhanced activation of the citric acid cycle (TCA cycle) for glycerol oxidati...
