Although heavy metals are naturally found in the environment as components of earth’s crust, environmental pollution by these toxic elements has increased since industrial revolution. Some them can be considered essential, they play regulatory roles different biological processes; but role other living tissues is not clear, and once ingested accumulate organism for long periods time causing adv...

Haloterrigena jeotgali is a halophilic archaeon within the family Natrialbaceae that was isolated from shrimp jeotgal, a traditional Korean salt-fermented food. A29(T) is the type strain of H. jeotgali, and is a Gram-negative staining, non-motile, rod-shaped archaeon that grows in 10 %-30 % (w/v) NaCl. We present the annotated H. jeotgali A29(T) genome sequence along with a summary of its featu...

Halorubrum lacusprofundi is an extreme halophile within the archaeal phylum Euryarchaeota. The type strain ACAM 34 was isolated from Deep Lake, Antarctica. H. lacusprofundi is of phylogenetic interest because it is distantly related to the haloarchaea that have previously been sequenced. It is also of interest because of its psychrotolerance. We report here the complete genome sequence of H. la...

Haloarchaea are salt loving microorganisms isolated from saline environments including ancient salt deposits and rock salt. A few haloarchaeal species have been reported to produce bacteriorhodopsin (BR) which works as a light driven proton pump. A haloarchaeal strain Halostagnicola larsenii IBS (MCC 2956) isolated from commercial Indian black salt (IBS) sample was employed for optimization of ...

Genomes are clearly suited for inferring common ancestry and for understanding ancestor–descendent relationships and interspecies gene transfer. Genomic evolutionary models can tell us a great deal about the processes that drive genome evolution, the mutational and selective pressures that lead to the genesis of biochemical pathways and operons, and the nature and extent of lateral gene transfe...
