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 philus for love or affinity. Overall, the name means "organism with a spherical body that gravitates to heat and to the weight of the water column."[2]

Physiology

Thermococcus 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]
