Survival of Methanogenic Archaea from Siberian Permafrost under Simulated Martian Thermal Conditions
Methanogenic archaea from Siberian permafrost complementary to the already well-studied methanogens from non-permafrost habitats were exposed to simulated Martian conditions. After 22 days of exposure to thermo-physical conditions at Martian low- and mid-latitudes up to 90% of methanogenic archaea f...
