Bacterial growth at the high concentrations of magnesium sulfate found in martian soils
(Mary Ann Liebert, 2012-02)The martian surface environment exhibits extremes of salinity, temperature, desiccation, and radiation that would make it difficult for terrestrial microbes to survive. Recent evidence suggests that martian soils contain ... -
Bacterial growth in brines formed by the deliquescence of salts relevant to cold arid worlds
(Mary Ann Liebert, Inc., 2022-01-11)Hygroscopic salts at Mars' near-surface (MgSO4, (per)chlorates, NaCl) may form brines by absorbing moisture from the atmosphere at certain times through the process of deliquescence. We have previously shown strong bacterial ... -
Bacterial growth in saturated and eutectic solutions of magnesium sulphate and potassium chlorate with relevance to Mars and the ocean worlds
(Cambridge University Press, 2019-01-28)Liquid water on Mars might be created by deliquescence of hygroscopic salts or by permafrost melts, both potentially forming saturated brines. Freezing point depression allows these heavy brines to remain liquid in the ... -
Bacterial growth tolerance to concentrations of chlorate and perchlorate salts relevant to Mars
(Cambridge University Press, 2017-07)The Phoenix lander at Mars polar cap found appreciable levels of (per)chlorate salts, a mixture of perchlorate and chlorate salts of Ca, Fe, Mg and Na at levels of similar to 0.6% in regolith. These salts are highly ... -
Cultivation and characterization of the bacterial assemblage of epsomic Basque Lake, BC
(Springer Nature, 2019)Athalassohaline waters that are rich in divalent ions are good analogues for the chemical environments of Mars and the ocean worlds. Sulfate salts, along with chlorides, are important in Mars regolith with Ca, Fe, Mg, and ...
