As microbial fuel cell (MFC) technology is getting nearer to practical applications, the microorganisms can convert chemical energy from a wide range of organic substances into electric current directly. In this paper, the MFC with a spherical configuration as cathode compartment was constructed. The MFC with a brush-shaped anode, platinum/carbon cathode, pre-treated Nafion 117 were constructed using pig farm wastewater as substrate. The biofilm analysis was used by bacterial community structure and diversity by denaturing gradient gel electrophoresis (DGGE). A benthic strain of proteobacteria was isolated and identified, wastewater was treated with proteobacteria to decrease the chemical oxygen demand, phosphorus, nitrogen and to produce electricity, which had an excellent electrogenic qualities.
