产甲烷古菌的分类及代谢途径研究进展

Methanogenic archaea typically refer to a class of anaerobic methanogenic archaea in the phylum Euryarchaeota, which primarily use carbon dioxide, acetate, and methyl compounds (disproportionation reaction of the methyl group) as substrates. As researchers around the world continue to study methanogenic archaea，they have discovered hydrogen-dependent methylotrophic methanogens, ，obligate methylthiotrophic methanogens, methylotrophic methanogens, alkane-utilizing methanogens, and methanogens that can produce methane while growing on methane fermentation. In addition to the phylum Euryarchaeota, scientists have also found methanogenic archaea in Ca. Thermoplasmatota, and TACK superphylum. Therefore, methanogenic archaea should be defined as a class of anaerobic methanogenic archaea that use carbon dioxide, acetate, methyl compounds, methoxyl compounds, and alkyl compounds as substrates, widely distributed in the phyla Euryarchaeota, Ca. Thermoplasmatota, ，and the TACK superphylum.
