Answer: Bacteria that create methane are known as methanogens. These bacteria are capable of degrading cellulose and other organic materials found in plant waste. The bacteria are utilised to make biogas, which may subsequently be used as a source of renewable energy. Methanogens are a type of anaerobic bacteria that produce methane.
Biogas is a gas that contains both methane and carbon dioxide. By anaerobic digestion of cellulosic plant parts, methanogens create methane, carbon dioxide, and hydrogen gas. As a result, methanogens aid in the production of biogas.
