摘　　要：产甲烷古菌通常指主要以CO_(2)、乙酸、甲基类化合物(甲基歧化型)作为底物的广古菌门Euryarchaeota中的一类厌氧代谢产甲烷的古核生物。随着全世界学者对产甲烷古菌进一步研究,陆续发现了氢依赖甲基型产甲烷古菌以及专性甲硫醇型、甲氧基型、烷基型和利用甲烷发酵生长同时又能产生甲烷的产甲烷古菌等;除广古菌门Euryarchaeota外,科学家也陆续在热原体门Ca.Thermoplasmatota和TACK超门中发现了产甲烷古菌。因此产甲烷古菌应定义为以二氧化碳、乙酸、甲基类化合物、甲氧基化合物、烷基类化合物为底物,广泛分布于广古菌门Euryarchaeota、热原体门Ca.Thermoplasmatota和TACK超门中的一类厌氧代谢产甲烷的古核生物。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.
