Detailed explanation-1: -Methanogens belong to archaebacteria. They are strict anaerobes . They are autotrophs which obtain both energy and carbon from decomposition products. They occur in marshy areas where they convert formic acid and carbon dioxide into methane with the help of hydrogen.
Detailed explanation-2: -Methanogens are distinguished from bacteria and archaea that may produce methane as a byproduct of metabolism by their obligate need to synthesize methane to conserve energy using the Wolfe Cycle [8]. By this distinction, all known methanogens, to date, belong to the euryarchaeal domain.
Detailed explanation-3: -Methanogenic Archaea are microorganisms that are capable of producing methane gas, a potential fuel source as well as a greenhouse gas that has been implicated in global warming.
