Thermococcus barophilus

Thermococcus barophilus is a barophilic and hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent. It is anaerobic and sulfur-metabolising, with type strain MPT.[1]

Nomenclature

The name Thermococcus barophilus has Greek roots, thermo for heat, kokkos for the spherical cells, baros for weight, and philos for loving. Overall, the name means "organism with a spherical body that gravitates to heat and to the pressure of the water column."[2]

Physiology

T. barophilus can grow at even higher temperatures if the pressure is high, as well. At an atmospheric pressure, it can grow at temperatures of 45-90 °C, with an optimal temperature of 85 °C, but it can grow at temperatures as high as 100 °C if the hydrostatic pressure is 15.0-17.5 MPa.[2]
