Thermococcus barophilus is a piezophilic and hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent.
[1] 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.
The genome sequence shows that it has the carboxydotrophic pathway and bears seven different hydrogenase complexes.
It has been found that, 378 genes are differentially expressed in T. barophilus under different pressure conditions.
