ABSTRACT
Microbial fuel cells (MFCs) an electricity producing device using waste-water treatment, biosensor, eco-friendly and low cost management of energy production. In this study, investigation power generation from waste water compared with their pure culture, mixed culture and different medium ingredients with microorganism. Enhance the power production with different ingredients like monosaccharide’s, nitrogen source and amino acids, these sources increasing the electron shuttle in the medium. Glucose (0.98 V), beef extract (0.85 V) and Leucine (0.92 V) exhibited maximum power production with the anodic chamber. Different electrode was used; platinum showed that maximum electron capturing in the anodic chamber. The SEM photography clearly showed that biofilm formation of microorganism on the electrode. The output power was compared with mixed culture to pure culture and different ingredients, thus bio electric power was retained maximum 1.03 V in pure culture from Morganella morganii and 1.2 V in mixed culture.
