Surviving Mars: The role of black fungus Rhinocladiella similis in understanding life in perchlorate-rich environments

The study of the survival of terrestrial microorganisms in Martian conditions, especially in the presence of perchlorates, offers crucial insights for astrobiology. This research investigates the resilience of the extremophilic black fungus Rhinocladiella similis to the exposure to magnesium perchlorate and UV-C radiation, simulating a Martian environment. The results show that R. similis, previously known for its remarkable tolerance to acidic conditions, exhibits significant resistance to UV-C radiation combined with perchlorate and high concentrations of magnesium perchlorate.
