Draft genome sequence of Caminibacter mediatlanticus strain TB-2T, an epsilonproteobacterium isolated from a deep-sea hydrothermal vent

Caminibacter mediatlanticus strain TB-2T [1], is a thermophilic, anaerobic, chemolithoauto-trophic bacterium, isolated from the walls of an active deep-sea hydrothermal vent chimney on the Mid-Atlantic Ridge and the type strain of the species. C. mediatlanticus is a Gram-negative member of the Epsilonproteobacteria (order Nautiliales) that grows chemolithoauto-trophically with H2 as the energy source and CO2 as the carbon source. Nitrate or sulfur is used as the terminal electron acceptor, with resulting production of ammonium and hydro-gen sulfide, respectively. In view of the widespread distribution, importance and physiologi-cal characteristics of thermophilic Epsilonproteobacteria in deep-sea geothermal environ-ments, it is likely that these organisms provide a relevant contribution to both primary prod-uctivity and the biogeochemical cycling of carbon, nitrogen and sulfur at hydrothermal vents. Here we report the main features of the genome of C. mediatlanticus strain TB-2T.
