Pressure retarded osmosis from hypersaline sources — A review
Desalination, 2017 Salinity gradient power has been identified as a promising new renewable energy technology, but previous attempts to commercialize the technology have failed due to low energy densities and power densities when using seawater as the saline water. One way

Acclimation to hypersaline water in a crab
Comparative Biochemistry and Physiology, 1963Abstract 1. 1. Groups of the mud crab Hemigrapsus oregonensis which had been exposed for prolonged periods to high salinity demonstrated better osmotic regulation in concentrated sea water than groups freshly removed from approximately normal sea water. 2. 2. This phenomenon is attributed to physiological acclimation. 3. 3.

Viruses from the Hypersaline Environment
2011Halophilic environments such as solar salterns and salt lakes are enriched in organisms belonging to the domain Archaea. The number of virus-like particles has also been shown to be high. Although most of the described haloarchaeal viruses are head–tail viruses, direct microscopic examination of environmental samples suggests more diversity.

Substrate Limitation for Methanogenesis in Hypersaline Environments
Astrobiology, 2012Motivated by the increasingly abundant evidence for hypersaline environments on Mars and reports of methane in its atmosphere, we examined methanogenesis in hypersaline ponds in Baja California Sur, Mexico, and in northern California, USA. Methane-rich bubbles trapped within or below gypsum/halite crusts have δ¹³C values near -40‰.

Cryptic Freshwater Ciliates in a Hypersaline Lagoon
Protist, 2003Ubiquitous dispersal of free-living microbial species implies that each and every ecosystem supports a 'seedbank' of microbial species that are imported by random dispersal. However, many of the microbial species present in any particular ecosystem will probably never thrive there because the local environment is unsuitable for their population growth.

Yeasts in Hypersaline Habitats
2017For a long time, halotolerant yeasts were known exclusively as contaminants of food preserved with high concentrations of salt or sugar. Their presence in natural thalassohaline hypersaline environments was unknown until 2000, when they were first reported to be active inhabitants of man-made solar salterns in Slovenia.

The Biogeochemistry of Hypersaline Microbial Mats
1995Microbial mats are structurally coherent macroscopic accumulations of microorganisms. Photosynthetic mats offer an opportunity to examine the dynamics of a complete microbial ecosystem. Microbial mats construct laminated “miniature reefs” called stromatolites, which occur typically as carbonate rocks and are among the oldest, most abundant fossil ...

Life in Hypersaline Environments
2016Many microorganisms are adapted to life at high-salt concentrations. Halophilic representatives are found in each of the three domains of life: Archaea, Bacteria, and Eukarya. Halophilic viruses exist as well. In NaCl-saturated brines such as found in the northern part of Great Salt Lake, Utah, in a few other natural salt lakes, and in saltern ...

Hypersaline, alkaline (>pH 9) lakes constitute a special class of extremely saline lakes in closed basins. The major ions are typically Na+, Cl-, HCO 3 - and CO 3 2- . Sulfate is proportionately low. The high concentrations of HCO 3 - and CO 3 2- are largely responsible for buffering these lakes at such high pH.
