A specific proteomic response of Sulfolobus solfataricus P2 to gamma radiations.

Sulfolobus solfataricus is an acidophilic hyperthermophilic crenarchaeon living at 80 °C in aerobic conditions. As other thermophilic organisms, S. solfataricus is resistant to gamma irradiation and we studied the response of this microorganism to this ionizing irradiation by monitoring cell growth, DNA integrity and proteome variations.
