Electricity supply in Nigeria has been a recurring decimal as huge amount of capital is involved. The aim of the study is to produce bioelectricity in a microbial fuel cell (MFC) from wastewaters. Wastewater from abattoir, fish pond, and stream were used to construct a microbial fuel cell and their physiochemical and microbiological properties were determined and the voltage of electricity produced was measured. Wastewaters were separately inoculated using pour plate to determine bacterial counts and type of bacteria in the wastewater. MFC abattoir waste gave the highest voltage (0.77V), followed by fish pond MFC with 0.58V, and least was stream MFC with 0.30V. The pH of the three wastewaters ranged from 6.24 – 5.60. The MFC with Abattoir wastewater had the highest electrical conductivity (15,150 μ/cm3), total dissolved solids (10,230), dissolved oxygen (8.20 mg/L), and BOD (6.00 mg/L), while MFC with stream waste water had the least electrical conductivity (600 μ/cm3), total dissolved solids (390), dissolved oxygen (4.20 mg/L), and BOD (2.00 mg/L). Connection in series gave a voltage 1.89V from three microbial fuel cells constructed with wastewaters from the abattoir. Wastewater from Abattoir obtained the highest count both for aerobic (2.56×1023 cfu/ml) and anaerobic (1.35×1023 cfu/ml), while wastewater from the stream gave the least count 1.32×1023 cfu/ml (aerobic) and at 6.55×1022 cfu/ml (anaerobic). Isolated bacterial species includes; Actinobacillus, Aeromonas, Bacillus, Citrobacter, Clostridium, Enterobacter, Enterococcus, Escherichia coli, Klebsiella, Micrococcus, Neisseria, Proteus, Psuedomonas aeruginosa, Samonella, Serrentia, Shigella, Staphylococcus and Streptococcus.
