In the taxonomy of microorganisms, the Methanomicrobiales are an order of the Methanomicrobia.^[1] Methanomicrobiales are strictly carbon dioxide reducing methanogens, using hydrogen or formate as the reducing agent.^[2] As seen from the phylogenetic tree based on 'The All-Species Living Tree' Project the family Methanomicrobiaceae is highly polyphyletic within the Methanomicrobiales.
