Species

Methanogenium is a genus of archaeans in the family Methanomicrobiaceae.[1] The type species is Methanogenium cariaci.[2]

Description and habitat

The species within Methanogenium are coccoid in shape and Gram-negatives and, like other methanogenic archaea, they produce methane from carbon dioxide, hydrogen or formate as substrates.[2] Although they occasionally have flagella, they are non-motile. They are strictly anaerobic, and can be found in marine and lake sediments that lack oxygen.[3]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[4] and National Center for Biotechnology Information (NCBI).[1]

16S rRNA-based LTP_01_2022[5][6][7] 53 marker proteins based GTDB 10-RS226[8][9][10]
