Complete genome sequence of the hyperthermophilic archaeon Thermococcus sp. strain CL1, isolated from a Paralvinella sp. polychaete worm collected from a hydrothermal vent

J Bacteriol. 2012 Sep;194(17):4769-70. doi: 10.1128/JB.01016-12.


Thermococcus sp. strain CL1 is a hyperthermophilic, anaerobic, and heterotrophic archaeon isolated from a Paralvinella sp. polychaete worm living on an active deep-sea hydrothermal sulfide chimney on the Cleft Segment of the Juan de Fuca Ridge. To further understand the distinct characteristics of this archaeon at the genome level, its genome was completely sequenced and analyzed. Here, we announce the complete genome sequence (1,950,313 bp) of Thermococcus sp. strain CL1, with a focus on H(2)- and energy-producing capabilities and its amino acid biosynthesis and acquisition in an extreme habitat.
