Where can halobacterium NRC-1 survive?

Halobacterium sp. NRC-1 is a non-pathogenic, halophilic archaea that thrives all over the world in high salt environments, including salt production facilities, brine inclusions in salt crystals, natural lakes and ponds, and salt marshes. Prior to 1990 H.

Is halobacterium Salinarum Gram positive or negative?

salinarum is a rod-shaped, single-celled, motile microorganism that can live with only light as an energy source due to its retinal protein bacteriorhodopsin (light driven proton pump). It is classified as gram-negative even though there is no cell wall, instead there is a single lipid bilayer surrounded by an S-layer.

How big is Halobacterium salinarum?

salinarum, strain NRC-1, comprises a 2.57 Mb chromosome (68% GC content) and two megaplasmids (58% GC content). A polyploid organism, Hbt. salinarum withstands high UV radiation partly due to robust DNA repair. The cytoplasm of Hbt.

How does halobacterium Salinarum obtain energy?

Halobacterium salinarum is a bioenergetically flexible, halophilic microorganism that can generate energy by respiration, photosynthesis, and the fermentation of arginine.

What NRC 1?

NRC-1 is an exceptionally halophilic archaeon that has given us much insight on elemental cellular processes common to all life forms because of its extreme lifestyle. Halobacterium sp. NRC-1 exists in extreme high concentrations of salt and can be found all over the world.

Is Halobacterium Salinarum harmful?

salinarium to pump large amounts of salt into its cell, but at the same time it can be a potentially lethal threat; if they are exposed to low molarity water, osmosis causes water to flood the cell causing the membrane to lyse or burst.

Is halobacterium Salinarum Halotolerant?

Halobacterium salinarum is an extremely halophilic marine obligate aerobic archaeon. salinarum to survive at such high salt concentrations has led to its classification as an extremophile.

Is halobacterium Salinarum harmful?

Is a higher or lower NRC better?

Noise Reduction Coefficient (NRC) A NRC is an average rating of how much sound an acoustic product can absorb. An NRC of 0 means that the product absorbs no sound. An NRC of 1 means that the product absorbs all sound. The higher the NRC, the better the product is at soaking up the sound.

Is halobacterium Salinarum an extremophile?

Halobacterium salinarum is an extremophile superhero on at least three counts. Halobacterium salinarum was originally grown in the laboratory from salted fish, but has been found in salt lakes, coastal salterns and ancient salt crystals.

What is the optimal growth temperature for Halobacterium NRC-1?

Its optimal growth temperature is known to be 42ºC, with NaCl optimum of 4.3 M. (1) The complete sequence of Halobacterium sp. NRC-1 harbors 2,571,010 bp (base pairs) containing 91 insertion sequences on behalf of 12 families.

How many plasmids does Halobacterium salinarum have?

Halobacterium salinarum (ATCC 700922 / JCM 11081 / NRC-1) has 1 chromosome and 2 plasmids. The chromosome has a very high GC content of 68 % whereas the plasmids have a lower GC content of 58.8 %. The chromosome of strain R1 is completely colinear and virtually identical to that of strain NRC-1.

What is the function of GVS in Halobacterium NRC-1?

The genome of Halobacterium sp. NRC-1 contains a large gene cluster—gvpMLKJIHGFEDACNO, which is necessary for the production of buoyant gas-filled vesicles (GVs) for the cell. (2) GVs in their intracellular structures are purely protein, unlike standard membranes that also contain lipids.

How does Halobacterium adapt to a high salinity environment?

Aerobic halophilic chemoorganotroph growing on the degradation products of less halophilic organisms as the salinity reaches near saturation. Halobacterium species have adapted to optimal growth under conditions of extremely high salinity (10 times that of sea water).
