From extreme environments on Earth to space: Buttiauxella sp. MASE-IM-9 and Salinisphaera shabanensis as new model organisms in Astrobiology

Mars analogue environments are some of the most extreme locations on Earth. Their unique combination of multiples extremes (e.g. high salinity, anoxia, and low nutrient availability) make them a valuable source of new polyextremophilic microbes in general and for exploring the limits of life. These are seen as vital sources of information for Astrobiology, with implications for planetary protection and the search for life outside our planet. [...
