Biological fuel cell technology can potentially be applied in waste water treatment and biological power generation. In this research paper,Saccharomyces cerevisiae were investigated as a biocatalyst in the anaerobic batch culture for generation of electrons and waste water treatment which is used in biological fuel cell. The initial chemical oxygen demand was 66,000 mg/lit and used as substrate for bioreactor. The substrate consumption was monitored for incubation period of 72 hours. Every 4 hours samples were withdrawn. The highest open circuit voltage achieved, was 0.25 V. The rate of consumption substrate in anaerobic condition indicated that cheese processing waste water can be used for power generation in biological fuel cell and also can be treated with high removal efficient of chemical oxygen demand.
