Isolation of psychrophilic halophiles from the Antarctic polar desert
Saline soils in the Dry Valley region of McMurdo Sound, Antarctica, contained bacteria showing salt tolerance or requirement. Soils were plated by the spread plate method on soil extract-peptone-yeast extract media to which sodium chloride had been added in concentrations from 0 to15 per cent …

Characteristic Raman Bands of Amino Acids and Halophiles as Biomarkers in Planetary Exploration
… exposure, both AA and halite entombed archaeal halophiles survived a combination of simulated martian conditions, e.g. freeze-thaw cycling resulted in a maximum of 20 % biomarker signal loss for AA. Halophilic microbes survived UV exposure up to 3.5 sols, though with a complete biomarker signal …

Functional Analysis of Novel Replication Protein a Homologs in the Euryarchaeota: Implications in the Evolution of Single -Stranded DNA Binding Proteins Across the Three Domains of Life
… which includes hyperthermophiles, mesophiles, halophiles, sulfate reducers, acidophiles, and methanogens, have reinvented RPAs many times and in the ensuing research molecular and biochemical approaches are used to study the structure and function of candidate RPAs from three archaeal species …

Isolation and characterization of new pterins from nonmethanogenic archaebacteria
… Two of these were identified in the extreme halophiles and were thus called halopterins. One of these halopterins is produced by Halobacterium salinarium, Halobacterium halobium, and Halococcus morrhuae and is called phosphohalopterin-1. It was given this name because it was the first …

Investigating the Biological Role and Binding Modes of Histone-Like Proteins of Halophilic Archaea
… were tested across four model species of halophiles, and the reasons for differences in performance for these approaches were analyzed. Methods that deliver efficient rRNA removal targeted to a particular species, or to halophilic archaea in general, are highlighted.</p><p>Together these …

Discovery of novel transaminases from halophilic microorganisms
… would render mesophilicenzymes ineffective. Halophiles are one such group of extremophile, adapted to survive at high salinity. Their enzymes also exhibit a number of other useful properties, such as thermotolerance, alkalitolerance, and tolerance to the presence of organic solvent.<br/><br/> …

Ancient Triassic Halite as a novel source of antibiotic chemical diversity
This thesis aimed to establish the potential of extremely halophilic microorganisms, isolated from Kilroot Salt Mine, as a reservoir of unexplored natural product chemistry with antimicrobial activity against the clinically relevant ESKAPE pathogens. The capacity of haloarchaea to modulate …
