UNLABELLED The thermodynamic availability of water (water activity) strictly limits microbial propagation on Earth, particularly in hypersaline environments. A considerable body of evidence indicates the existence of hypersaline surface waters throughout the history of Mars; therefore it is assumed that, as on Earth, water activity is a major limiting factor for martian habitability. However, the differing geological histories of Earth and Mars have driven variations in their respective aqueous…

Microbes from Brine Systems with Fluctuating Salinity Can Thrive under Simulated Martian Chemical Conditions

This study shows microbes from fluctuating brines can survive and grow in simulated martian water chemistry, but further investigations are required to further define the potential habitability under past martian conditions.

Halophilic responses to a range of salts and their relevance to Mars

This Thesis investigated the survival of salt-tolerant microorganisms in environments where salts other than NaCl are present, with the aim being to shed new light on the martian astrobiological

An Ionic Limit to Life in the Deep Subsurface

Under certain circumstances, complex brines can establish a hard limit to microbial replication in the deep biosphere, highlighting the potential for subsurface uninhabitable aqueous environments at depths far shallower than a geothermally-defined limit to life.

Mars' surface is not universally biocidal.

The low temperatures of the Mars surface are not conducive to metabolic activity, but the biophysical sophistication and robust stress biology of many terrestrial microbes, and the protection afforded by Martian conditions, are likely to ensure the long-term viability of some extremophilic microbes if transported to Mars.

The Bioburden and Ionic Composition of Hypersaline Lake Ices: Novel Habitats on Earth and Their Astrobiological Implications.

We present thermophysical, biological, and chemical observations of ice and brine samples from five compositionally diverse hypersaline lakes in British Columbia's interior plateau. Possessing a

Bioenergetic Constraints on Microbial Hydrogen Utilization in Precambrian Deep Crustal Fracture Fluids

ABSTRACT Precambrian Shield rocks host the oldest fracture fluids on Earth, with residence times up to a billion years or more. Water–rock reactions in these fracture systems over geological time

NaCl-saturated brines are thermodynamically moderate, rather than extreme, microbial habitats.

The evidence is surveyed that NaCl-saturated brines are biologically permissive, fertile habitats that are thermodynamically mid-range rather than extreme and may be that the finite solubility of NaCl has stabilised the genetic composition of halophile populations and limited the action of natural selection in driving halophile evolution towards greater xerophilicity.

Habitability of Mars: How Welcoming Are the Surface and Subsurface to Life on the Red Planet?

Mars is a planet of great interest in the search for signatures of past or present life beyond Earth. The years of research, and more advanced instrumentation, have yielded a lot of evidence which

Building a Geochemical View of Microbial Salt Tolerance: Halophilic Adaptation of Marinococcus in a Natural Magnesium Sulfate Brine

This strain of Marinococcus isolated from the magnesium and sulfate-dominated Basque Lakes (British Columbia, Canada) was the sole isolate obtained after exposure to exceptionally high levels of Mg2+ and SO42- ions, and grew at extremes of ionic strength not normally encountered in Na+/Cl- brines.

The Microbial Community of a Terrestrial Anoxic Inter-Tidal Zone: A Model for Laboratory-Based Studies of Potentially Habitable Ancient Lacustrine Systems on Mars

The results from this study suggest that the microbial community from an anoxic inter-tidal zone is a plausible terrestrial analogue for studying habitability of fluvio-lacustrine systems on early Mars, using laboratory-based simulation experiments.

Magnesium sulphate salts and the history of water on Mars

It is found that crystalline structure and H2O content are dependent on temperature–pressure history, that an amorphous hydrated phase with slow dehydration kinetics forms at <1% relative humidity, and that equilibrium calculations may not reflect the true H 2O-bearing potential of martian soils.

Multiplication of microbes below 0.690 water activity: implications for terrestrial and extraterrestrial life.

Water activity in relation to the limits of Earth's present-day biosphere; the possibility of microbial multiplication by utilizing water from thin, aqueous films or non-liquid sources; whether prokaryotes were the first organisms able to multiply close to the 0.605-aw limit; and whether extraterrestrial aQueous milieux of ≥ 0.605 aw can resemble fertile microbial habitats found on Earth.

Physicochemical properties of concentrated Martian surface waters

Understanding the processes controlling chemical sedimentation is an important step in deciphering paleoclimatic conditions from the rock records preserved on both Earth and Mars. Clear evidence for

Limits of life in MgCl2-containing environments: chaotropicity defines the window.

The exceptional chaotropicity of MgCl(2) is document here, and it is shown that this property, rather than water activity reduction, inhibits life by denaturing biological macromolecules, in hypersaline environments.

Water and Brines on Mars: Current Evidence and Implications for MSL

Liquid water is a basic ingredient for life as we know it. Therefore, in order to understand the habitability of other planets we must first understand the behavior of water on them. Mars is the most

Limits to Life at Low Temperatures and at Reduced Water Contents and Water Activities, and Atmospheric Constraints on the Evolution of Metabolism are studied.

Sulfates hydrating bulk soil in the Martian low and middle latitudes

The evidence for sulfate‐bearing strata, across Late‐Noachian to Amazonian eons, suggests a central role for sulfates in acidity and salinity of Martian paleofluids and the planet's habitability.
