These microorganisms are referred to as methanogenic hydrogenotrophs because they consume hydrogen and produce methane. Such microorganism are thought to be among the earliest forms of life on Earth.
Abstract: Here we show methanogenic growth by a member of the lineage Korarchaeia within the phylum Thermoproteota (TACK superphylum). Following enrichment cultivation of ‘Candidatus Methanode ...
which in turn inhibited hydrogenotrophic methanogenesis and shifted the predominant methanogenic pathway towards acetoclastic methanogenesis at free ammonia over 1.5 g/l. C/N increases to 25 and 29 ...
