Halophilic & Halotolerant Prokaryotes in Humans
Future Microbiology, 2018Halophilic prokaryotes are described as microorganisms living in hypersaline environments. Here, we list the halotolerant and halophilic bacteria which have been isolated in humans. Of the 52 halophilic prokaryotes, 32 (61.54%) were moderately halophilic, 17 (32.69%) were slightly halophilic and three (5.76%) were extremely halophilic prokaryotes.

Dunaliella salina Hsp90 is halotolerant
International Journal of Biological Macromolecules, 2015Dunaliella salina is a unicellular green alga with exceptional halotolerance. Although the D. salina cells are capable to proliferate in hypersaline medium, the intracellular salt concentrations are maintained at a low level. Thus the extracellular but not intracellular Dunaliella proteins are expected to be highly halotolerant.

Molecular bases of protein halotolerance
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2014Halophilic proteins are stable and function at high salt concentration. Understanding how these molecules maintain their fold stable and avoid aggregation under harsh conditions is of great interest for biotechnological applications. This mini-review describes what is known about the molecular determinants of protein halotolerance.

Hydroxylamine reductase of a halotolerant micrococcus
Biochimica et Biophysica Acta, 1960A hydroxylamine reductase of hemoprotein nature was prepared from a strain of halotolerant Micrococcus. The hydroxylamine reductase was shown to contain iron as its active center. Manganese ions at 0.5 mM concentration activate the reaction about 3 to 4 times when the activity is measured by the reduced methylene blue method; these ions possibly ...

Halophily and halotolerance in cyanophytes
Origins of Life, 1980The survival, growth and distribution of organisms in hypersaline environments is discussed using cyanophytes (cyanobacteria) as examples. The distinction between halophilic (Na+-requiring) and halotolerant organisms is not adequate to describe the entire spectrum of adaptations to salt.

Mechanisms of Halotolerance in Microorganisms
CRC Critical Reviews in Microbiology, 1987Microorganisms have the ability to adapt to a wide range of NaCl concentrations. In general the NaCl tolerance shown by microbes far exceeds the salt tolerance of any other organism, procryote or eukaryote. There are at least three mechanisms available for adaptation to different salt concentrations.

Halotolerance mechanisms in salt‑tolerant cyanobacteria
2023Cyanobacteria are ubiquitously distributed in nature and are the most abundant photoautotrophs on Earth. Their long evolutionary history reveals that cyanobacteria have a remarkable capacity and strong adaptive tendencies to thrive in a variety of conditions.

β‐Galactosidase from halotolerant Aspergillus tubingensis GR1 was purified by two‐step purification process comprising ammonium sulfate precipitation followed by size exclusion chromatography (SEC). The recovery of β‐galactosidase after SEC was found to be 1.40% with 58.55‐fold increase in specific activity.
