Keywords: Microbial fuel cell, Abattoir, Wastewater and Electricity
The potential of generating electricity from waste water obtained from an abattoir through microbial fuel cell technology was evaluated. Results obtained revealed that the consortium of bacteria indigenous to the waste water had the ability to produce electricity. The amount of current generated increased withincrease in incubation duration such that at 48 hof incubation, a current of 17.45mA was generated by the bacterial consortium. The bacteria isolated from the waste water were Pseudomonasaeruginosa, Klebsiella sp., Bacillus sp., Escherichiacoli and Proteus sp. The maximum electrical current generated by each of this bacterium was0.3, 0.01, 0.01, 0.9 and 0.05 mArespectively. Generally, the amount of current generated in set up that contained the consortium of bacteria was significantly higher (at p < 0.05) than that which contained individual pure bacterial isolate. Also, there was a significant difference in the amount of current produced by each pure isolate. Conclusively, this study demonstrates that abattoir waste water has enough strength for the generation of electric current and its utilization in microbial fuel cells hold promise towards sustained energy generation and could be an attractive alternative to reduce the cost of generating electricity.
