Previously, phylogenetic approaches using large datasets revealed that methanogens can be grouped into two classes, “Class I” and “Class II”. However, some deep relationships were not resolved.
Web9 jul. 2024 · Methanogenesis is an anaerobic respiration that generates methane as the final product of metabolism. In aerobic respiration, organic matter such as glucose is oxidized to CO 2, and O 2 is reduced to H 2 O. In contrast, during hydrogenotrophic methanogenesis, H 2 is oxidized to H +, and CO 2 is reduced to CH 4.
