Biogas Production from Cow Dung By Using Methanogenic Bacteria

Abstract

Rapid urbanisation and depletion of fossil fuels lead us to search for an alternative means of fuel production from renewable resources. Substituting fossil fuel through biofuel has become crucial for constant or green energy development. Since being produced from renewable resources, biofuel is better for the environment with lesser emissions compared to petroleum fuel. In the present study, a new, eco-friendly approach for biogas production from food waste was attempted. For the purpose, the methanogenic bacteria isolated from cow dung was used as inoculum for the production of biogas. The slurry was further characterized for the presence of bacteria and the isolated bacteria were characterized biochemically. The gas chromatography was used to quantitate the amount of biogas produced. The results of the present study enabled in identifying a new, eco-friendly and cost-effective means of producing biogas from food waste, using methanogenic bacteria isolated from cow dung
