Halobacterium salinarum is a halophilic (salt-loving) archaeon that grows in salt concentrations near or at saturation. Although isolated from salted fish a century ago, it was the 1971 discovery of bacteriorhodopsin, the light-driven proton pump, that raised interest in Hbt. salinarum across a range of disciplines, including biophysics, chemistry, molecular evolution and biotechnology.

halobacteriumsalinarum BIOLOGÍA y GEOLOGÍA

Halobacterium salinarum, formerly known as Halobacterium cutirubrum or Halobacterium halobium, is an extremely halophilic marine obligate aerobic archaeon. Despite its name, this is not a bacterium, but a member of the domain Archaea. It is found in salted fish, hides, hypersaline lakes, and salterns.As these salterns reach the minimum salinity limits for extreme halophiles, their waters.

Halobacterium salinarum. In Halobacterium salinarium the major wall component is a glycoprotein, each molecule of which contains several di- and trisaccharide units linked O-glycosidically to protein and one oligosaccharide chain linked N-glycosidically to an asparagine residue in the protein chain.

Halobacterium salinarum is an extremophile superhero on at least three counts.It can: (1) start to grow only when salt concentrations are three times higher than seawater - and flourish when the main salt in seawater (sodium chloride, NaCl) starts to come out of solution; (2) withstand extremely high doses of radiation; and (3) survive for thousands and possibly millions of years entombed.

Halophiles, such as Halobacterium salinarum, can generate an electrochemical proton gradient across the membrane by respiration and/or the light driven proton pump bacteriorhodopsin (Michel and Oesterhelt, 1980).This organism generates a SMF by an H + /Na + antiporter that expels the sodium ions and thus keeps the cytoplasm relatively free of sodium (Murakami and Konishi, 1988).

Halobacterium salinarum R1 (DSM 671) is the hyperhalophilic archaea strain used for the study. Cells were grown at 37 °C, with shaking at 110 rpm in standard hypersaline medium containing 4.2 M NaCl, 160 mM MgSO 4, 10 mM Trisodium citrate and 26 mM KCl (Oesterhelt and Stoeckenius 1974) under aerobic conditions. For salt stress shock experiment.

Halobacterium (common abbreviation Hbt.) is a genus in the family Halobacteriaceae.. The genus Halobacterium ("salt" or "ocean bacterium") consists of several species of Archaea with an aerobic metabolism which requires an environment with a high concentration of salt; many of their proteins will not function in low-salt environments. They grow on amino acids in their aerobic conditions.

Halobacterium salinarum NRC-1 (H. salinarum) is an extremely halophilic archaeon that requires high salt concentrations for cellular integrity and growth, and is widely found in hypersaline.

Halobacterium

Halobacterium salinarum is an extremely halophilic archaeon that is widely distributed in hypersaline environments and was originally isolated as a spoilage organism of salted fish and hides. The type strain 91‐R6 (DSM 3754 T) has seldom been studied and its genome sequence has only recently been determined by our group.The exact relationship between the type strain and two widely used model.

Halobacterium salinarum is a halophilic (salt-loving) member of the Archaea that grows in concentrations of sodium chloride (NaCl) near or at saturation. Initially isolated from salted fish a century ago, Hbt. salinarum first drew general attention with the 1971 discovery of bacteriorhodopsin, the light-driven proton pump isolated from the purple membrane of this organism. Since then, studies.

The genome of Halobacterium salinarum strain NRC-1 has been unraveled by Ng et al.. Halobacterium has a chromosome of 2 Mb having 68% GC and a number of megaplasmids with an average of 58% GC. Strain R1 has 4 megaplasmids and strain NRC-1 is reported to have 2 megaplasmids. Approximately 2,837 proteins are encoded by the whole genome of strain R1.
