HF1 and HF2: Novel Bacteriophages of Halophilic Archaea
Virology, 1993Two novel halophilic archaebacterial bacteriophages, HF1 and HF2, were isolated from an Australian solar saltern. They were morphologically identical with icosahedral-shaped heads (diameter 58 nm) and contractile tails (length 94 nm). Other similarities included sensitivity to reduced ionic conditions, similar protein profiles by SDS-PAGE, and dsDNA ...

Nitrate Assimilation in Halophilic Archaea
2004Nitrate is an important inorganic nitrogen source for plants and microorganisms. The physiology, enzymology and genetics of nitrate assimilation have been well studied in plants and bacteria (Campbell 1996; Lin and Stewart 1998); nonetheless, little is known at the biochemical, genetic or structural level of this process in halophilic Archaea.

Bioprospecting Archaea: Focus on Extreme Halophiles
2016In 1990, Woese et al. divided the Tree of Life into three separate domains: Eukarya, Bacteria, and Archaea. Archaea were originally perceived as little more than “odd bacteria” restricted to extreme environmental niches, but later discoveries challenged this assumption. Members of this domain populate a variety of unexpected environments (e.g.

Proteases Produced by Halophilic Bacteria and Archaea
2005Proteases from halophilic microorganisms present the advantage of being stable at high salinities, constituting interesting enzymes from a biotechnological point of view. To maintain osmolarity in saline environments the microorganisms adopt mainly two strategies, one followed by most moderately halophilic bacteria, accumulating organic compatible ...

25 Characterization of Lipids of Halophilic Archaea
2006Publisher Summary One- or two-dimensional thin-layer chromatography (TLC) is a useful technique for the rapid characterization of the lipids present in halophilic archaeal isolates. Mass spectrometry and nuclear magnetic resonance (NMR) spectroscopic techniques are powerful analytical methods in studies of structural characterization of lipid ...

Enzyme diversity in halophilic archaea.
Microbiologia (Madrid, Spain), 1995The halophilic archaea display a considerable extent of enzyme diversity. The presence or absence of certain enzymatic activities is closely linked with the taxonomic status of the strains investigated. Thus, Halobacterium species such as Hb. salinarium, Hb. halobium, and Hb.

The Enigma of Square and Triangular Halophilic Archaea
1999An overview of the prokaryotic world shows that the morphological variety among bacteria is limited, and most prokaroytic microorganisms, whatever their taxonomic position or their physiological properties might be, can be classified in a very limited number of morphological types: rods, cocci, and spirilla.

BIODEGRADATION OF POLYCYCLİC AROMATIC HYDROCARBONS BY HALOPHİLİC BACTERİA AND HALOPHİLİC ARCHAEA
2016Polycyclic aromatic hydrocarbons are widespread in various ecosystems and arepollutants of great concern due to their potential toxicity, mutagenicity andcarcinogenicity. Because of their hydrophobic nature, most PAHs bind toparticulates in soil and sediments, rendering them less available forbiological uptake.
