  • Title: Methanogenesis: surprising molecules, microorganisms and ecosystems.
    Author: Vogels GD, van der Drift C, Stumm CK, Keltjens JT, Zwart KB.
    Journal: Antonie Van Leeuwenhoek; 1984; 50(5-6):557-67. PubMed ID: 6442121.
    Abstract:
    Methanogenesis involves a novel set of coenzymes as one-carbon and electron carriers. Consequently, metabolic processes of methanogens deviate from those present in non-methanogenic bacteria. Methanogenic bacteria can be classified on the basis of substrate utilization. Group I (24 species) grows at the expense of hydrogen plus CO2 and/or formate and group II (7 species) uses methanol and/or acetate. Hydrogen-consuming methanogens are found as epi- or endosymbionts of anaerobic ciliates.
