Definition of methanogenesis in English:



  • [mass noun] The production of methane by bacteria or other living organisms.

    • ‘Dolomite as a possible product of bacterial methanogenesis is absent in sediments from the Marnes Bleues Formation.’
    • ‘Selenoproteins are relevant to the controversy over the metabolic features of the archaeal ancestor of eukaryotes because, among archaea, they facilitate autotrophic growth and methanogenesis.’
    • ‘Some Archaea exhibit unique features in the living world, such as methanogenesis or the ability to grow at temperatures above 95°C or at pHs as low as 0.’
    • ‘They conclude that the calcitic core of the concretions formed in the sulphate reduction zone, whereas the dolomite of the intermediate parts of the concretion formed largely from methanogenesis and iron reduction.’
    • ‘In the marine environment, methanogenesis is restricted by competition with anaerobic sulphate-reducing bacteria, which use similar substrates.’
