Methanomethylophilus alvi is a species of methanogenic archaea in the family Methanomethylophilaceae. It is the type and only validly published species of the genus Methanomethylophilus , first isolated from the human gastrointestinal tract and formally described in 2023. [1]
The species epithet alvi is derived from the Latin genitive form of "alvus", meaning "of the bowels", referencing its intestinal origin. [1]
M. alvi is a small, coccoid-shaped, archaeon that forms colonies under strictly anaerobic conditions. It performs hydrogenotrophic methanogenesis using methylated compounds such as methanol, monomethylamine, dimethylamine, and trimethylamine as substrates, with molecular hydrogen serving as the electron donor It does not utilize acetate or carbon dioxide/hydrogen. Optimal growth occurs at 37°C, under conditions typical of the human gut microbiome. [1]
