Complete genome sequence of Methanoplanus petrolearius type strain (SEBR 4847(T))

Methanoplanus petrolearius Ollivier et al. 1998 is the type strain of the genus Methanoplanus. The strain was originally isolated from an offshore oil field from the Gulf of Guinea. Members of the genus Methanoplanus are of interest because they play an important role in the carbon cycle and also because of their significant contribution to the global warming by methane emission in the atmosphere. Like other archaea of the family Methanomicrobiales, the members of the genus Methanoplanus are able to use CO(2) and H(2) as a source of carbon and energy; acetate is required for growth and probably also serves as carbon source. Here we describe the features of this organism, together with the complete genome sequence and annotation. This is the first complete genome sequence of a member of the family Methanomicrobiaceae and the sixth complete genome sequence from the order Methanomicrobiales. The 2,843,290 bp long genome with its 2,824 protein-coding and 57 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.
