Species InformationThe Thermococcus barophilus MP genome is 2.06 Million bp long and contains approximately 2315 predicted genes.
Taxonomy: Archaea; Euryarchaeota; Thermococci; Thermococcales; Thermococcaceae; Thermococcus.
Sequencing: The sequence was released Dec 20 2010 by the J. Craig Venter Institute, and was described in J Bacteriol 193:1481-2 (2011) Vannier P, Marteinsson VT, Fridjonsson OH, Oger P, Jebbar M,. "Complete genome sequence of the hyperthermophilic, piezophilic, heterotrophic, and carboxydotrophic archaeon Thermococcus barophilus MP."
Abstract: Thermococcus barophilus is a hyperthermophilic, anaerobic, mixed heterotrophic, and carboxydotrophic euryarchaeon isolated from the deep sea hydrothermal vent Snakepit site on the mid-Atlantic ridge at a depth of 3,550 m. T. barophilus is the first true piezophilic, hyperthermophilic archaeon isolated, having an optimal growth at 40 MPa. Here we report the complete genome sequence of strain MP, the type strain of T. barophilus. The genome data reveal a close proximity with Thermococcus sibiricus, another Thermococcus isolated from the deep biosphere and a possible connection to life in the depths....

Abstract: A novel barophilic, hyperthermophilic, anaerobic sulfur-metabolizing archaeon, strain MPT (T = type strain), was isolated from a hydrothermal vent site (Snakepit) on the Mid-Atlantic Ridge (depth, 3550 m). Enrichments and isolation were done under 40 MPa hydrostatic pressure at 95 degrees C. Strain MPT was barophilic at 75, 80, 85, 90, 95 and 98 degrees C, and was an obligate barophile between 95 and 100 degrees C (Tmax). For growth above 95 degrees C, a pressure of 15.0-17.5 MPa was required. The strain grew at 48-95 degrees C under atmospheric pressure. The optimal temperature for growth was 85 degrees C at both high (40 MPa) and low (0.3 MPa) pressures. The growth rate was twofold higher at 85 degrees C under in situ hydrostatic pressure compared to at low pressure. Strain MPT cells wer... [Click above reference link for full abstract]
