Methanococcus

Methanococcus is a genus of coccoid methanogens of the family Methanococcaceae.

The latter was discovered at the base of a “white smoker” chimney at 21°N on the East Pacific Rise[2] and it was the first archaeal genome to be completely sequenced, revealing many novel and eukaryote-like elements.

[3] 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).
