| Species | |
Methanobrevibacter is a genus of archaea in the family Methanobacteriaceae.[1] The species within Methanobrevibacter genus are strictly anaerobic and produce methane through the reduction of carbon dioxide via hydrogen with some also able to utulize formate. Methanobrevibacter species exclusively inhabit digestive tract of various animals such as cattle, termites, and primates including humans [2]. As part of cattle gut microbiome, Methanobrevibacter species responsible for about 20% of annual methane emission to the atmosphere [3].
Nomenclature
The name Methanobrevibacter has Latin and Greek roots. Methanum is Latin for methane, brevi is Latin for short, and bacter is Greek for bar or rod.[4] This word typically describes these bacteria which are short, rod shaped and produce methane.
Professional publications use the abbreviations M., Mbb., and Mbr., as in M. smithii,[5] Mbb. smithii,[6] and Mbr. smithii.[7]
Phylogeny
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[8] and National Center for Biotechnology Information (NCBI).[1]
