Extremophiles are organisms that can survive in adverse conditions. Over the last decades, interest in microorganisms with such abilities has been increasing, mostly because conclusions regarding extraterrestrial
life might be drawn from studying their molecular adaptations. The aim of this report is to establish a connection between several polyextremophiles that could survive under Martian conditions and the microhabitats
where they would be located. It was concluded that radioresistant microorganisms have a high probability of
surviving on the surface of Mars, namely Methanosarcina soligelidi SMA-21 and D. radiodurans. The liquid
water found on the subsurface of Mars represents a microhabitat where both methanogens M. bakeri and M.
mmaripaludis as well as cyanobacteria Nost commune could thrive. Another cyanobacteria, Chroococcidiopsis
sp was found to have the necessary characteristics to be able to thrive on both microhabitats. Identifying the
species of polyextremophiles that are most likely to survive on Mars is of crucial importance, particularly in
the development of future life-seeking space missions.
