As microbial fuel cell (MFC) technology is getting nearer to practical applications, the mi-croorganisms 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 dena-turing gradient gel electrophoresis (DGGE). A benthic strain of proteobacteria was isolated and identified, wastewater was treated with proteobacteria to decrease the chemical ox-ygen demand, phosphorus, nitrogen and to produce electricity, which had an excellent electrogenic qualities.
