Fig. 1From: Comparative analysis of deep sequenced methanogenic communities: identification of microorganisms responsible for methane productionAn overview of methanogenesis pathways from: carbon dioxide (hydrogenotrophic pathway); acetate (acetoclastic pathway); mono-, di-, tri- methylamine and methanol (methylotrophic pathway). Initial substrates for methane production and the final product were marked by bold capital letters. Additionally, initial substrates were underlined and the final product was marked with a frameBack to article page
