Cow dung and water is mixed and the slurry is fed into the biogas plant for digestion by microbes. The person performing the process shares that there is no need to provide inoculum for it. Why? What is the role of microbes at the source? Under which condition will they be most active and effective?

Answer:
If the slurry of cow dung and water is fed into the biogas plant there is no need to provide inoculum for biogas production because the cow dung or excreta of cattle in itself contain a large number of anaerobic methanogenic bacteria. Therefore the slurry (cow dung and water) can be used for generation of biogas. These bacteria breakdown the cellulosic material present in the rumen of cattle anaerobically and produce large amount of methane along with CO2 and water.
