| Since the discovery of hydrothermal vents in 1977, a small number of studies have allowed the isolation and characterization of microorganisms that can withstand high pressures and temperatures. Among these, Pyrococcus yayanosii, a hyperthermophilic archaea of the order Thermococcales, came from the Ashadze site (Mid-Atlantic Ridge) at 4100 m depth. This species represents the first organism both hyperthermophilic and strict piezophilic described to date. It cannot divide at pressures below 20 MPa and its optimal growth pressure is 52 MPa. In order to study the mechanisms used by this species to grow under high pressures, transcriptomics (DNA chips) and proteomics (LC-MS/MS) experiments have been carried out at different pressures, notably sub- and... |
