Airborne Halophilic and Non-Halophilic Microbial Communities in an Underground Salt Mine Affected by Seasonal Environmental Fluctuations. [PDF]

Environ Microbiol Rep
This study tests seasonal controls on airborne microbes in the UNESCO‐listed Bochnia Salt Mine. In summer, relative humidity exceeded the halite deliquescence threshold, coinciding with higher NaCl aerosol and greater densities of halophilic microbes; in winter, humidity stayed below deliquescence and halophilic microbes declined at least 13‐fold while

DNA Repair and Photoprotection: Mechanisms of Overcoming Environmental Ultraviolet Radiation Exposure in Halophilic Archaea [PDF]

Front Microbiol, 2017
Halophilic archaea push the limits of life at several extremes. In particular, they are noted for their biochemical strategies in dealing with osmotic stress, low water activity and cycles of desiccation in their hypersaline environments. Another feature

Halophilic Archaea Mediate the Formation of Proto-Dolomite in Solutions With Various Sulfate Concentrations and Salinities [PDF]

Front Microbiol, 2019
In the past several decades, sulfate concentration and salinity have been considered to be the two essential hydrochemical factors in the formation of dolomite, yet arguments against this hypothesis have existed simultaneously.

Opsin-Mediated Inhibition of Bacterioruberin Synthesis in Halophilic Archaea. [PDF]

J Bacteriol, 2017
ABSTRACTHalophilic archaea often inhabit environments with limited oxygen, and many produce ion-pumping rhodopsin complexes that allow them to maintain electrochemical gradients when aerobic respiration is inhibited. Rhodopsins require a protein, an opsin, and an organic cofactor, retinal.

Halorarius litoreus gen. nov., sp. nov., Halorarius halobius sp. nov., Haloglomus halophilum sp. nov., Haloglomus salinum sp. nov., and Natronomonas marina sp. nov., extremely halophilic archaea isolated from tidal flat and marine solar salt

Frontiers in Marine Science, 2023
Five novel halophilic archaeal strains, named BND22T, ZY10T, ZY41T, ZY58T, and ZY43T, were isolated from the coastal saline sediment of the intertidal zone located in Qingdao and the natural sea salt produced from Huanghua marine solar saltern, PRChina ...

Metabolism of halophilic archaea [PDF]

Extremophiles, 2008
In spite of their common hypersaline environment, halophilic archaea are surprisingly different in their nutritional demands and metabolic pathways. The metabolic diversity of halophilic archaea was investigated at the genomic level through systematic metabolic reconstruction and comparative analysis of four completely sequenced species: Halobacterium ...

Regulated Polyploidy in Halophilic Archaea [PDF]

PLoS ONE, 2006
Polyploidy is common in higher eukaryotes, especially in plants, but it is generally assumed that most prokaryotes contain a single copy of a circular chromosome and are therefore monoploid. We have used two independent methods to determine the genome copy number in halophilic archaea, 1) cell lysis in agarose blocks and Southern blot analysis, and 2 ...

Effects of chaotropic salts on global proteome stability in halophilic archaea: Implications for life signatures on Mars.

Environmental Microbiology, 2023
Halophilic archaea thriving in hypersaline environments, such as salt lakes, offer models for putative life in extraterrestrial brines such as those found on Mars.

Organic Solvent Tolerance of Halophilic Archaea [PDF]

Bioscience, Biotechnology, and Biochemistry, 2003
Organic solvent tolerance was tested in type strains of type species of the sixteen genera of Halobacteriaceae, the halophilic archaea. Most of the strains were observed to grow in the presence of hexylether (log Pow=5.1), but none grew in the presence of n-octane (log Pow=4.9) except Halogeometricum borinquense JCM 10706T and Halorubrum saccharovorum ...
