Abstract

During the project MASE (Mars Analogues for Space Exploration) several isolates were obtained and these strains were subjected to Mars relevant environmental stress factors in the laboratory under controlled conditions; e.g. radiation, low water activity, high salt concentrations, oxidizing compounds. First screening steps were always the microorganisms’ tolerance to survive times of desiccation and exposure to ionizing radiation. Both treatments were performed under anoxic conditions.
