With initial concentration of 200μgL(-1), spontaneous As(III) oxidation is realized completely during 7 days operation in single-chamber microbial fuel cells (MFCs) in the present study, with the maximum power density of 752.6±17mWm(-2).  They interact together and are responsible for As(III) oxidation and bioelectricity generation in MFCs.
