Explain the role of microbes in biogas production.

Explanation

Biogas is a mixture of different gases like methane (63%) with `CO_(2)` and hydrogen. The agricultural wastes, sewage sludge, food wast etc., form the raw materials for the production of biogas. In biogas production, the organic are converted into gas and organic fertilizers by microbes under anaerobic conditions.
Methanogens are the methane producing bacteria, responsible for biogas production. Methanobacterium is the common bacteria used for the production of biogas, whic burns with a blue flame. The bacteria are present in anaerobic sludge and rumen of the cattle.
The excreta of cattle is called as .Gobar., which form the inoculum of the anaerobic process in the biogas unit. The biogas/gobar gas is also generated by the anaerobic decomposition of cattle dung, by the methanogenic bacteria.
