英文摘要	Five soil microbial fuel cells (SMFCs) with graphite felt, aluminium sheet, activated carbon fibre felt, graphite paper and carbon cloth as anodes were constructed using the petroleum hydrocarbon polluted soils as substrates. After 115 days of operation, the SMFC with graphite felt anode performed the best in both bioelectricity output and removal of target pollutants, with the bioelectricity output parameters of 345 mV for stable voltage, 24.0 mW/m(2) for power density and 774 Q for internal resistance, and the removal rates of 59.14 % for total petroleum hydrocarbon, 61.65 % for anthracene, and 55.92 % for pyrene, respectively. The conductivity of the material was the key factor affecting the electron transfer rate of the anode, which determined the electric acclimation and screening intensity of SMFC to soil microbes, leading to the growth and succession of the electricigens-dominanted anode microbial community with various abundances of phyla and genera. The surface structure of the anode material played a critical role in the internal resistance of SMFC through affecting the mass transfer of substrate and metabolites, and it might also change the abundance of microbes especially those non-electricigens on the community through different adhesion.
