Description and Significance

Grows in high salt concentrated water, Uses ATP synthesis from a sunlight driven photoreceptor protein, Important for assisting with development of optogenetics, Salt tolerant (NCBI Taxonomy Browser)

Genome Structure

In the genome: Two chromosomes and one plasmid, Circular shaped microbe (Oren, 1983), Proteins functioning in high saline/low temperature environments, Lives in hostile environments with immense solar exposure and highly concentrated seawater (Bodaker et al. 2010).

Cell Structure, Metabolism and Life Cycle

On the surface: AR3 (Archaerhodopsin) retrieves energy from sun (NCBI Taxonomy Browser), Growth of the microbe stems from high ion concentration of Mg2+, Create salt-tolerant bacteria, Lives in a 10x higher sodium concentrated environment, Presents an acidic level pH of 6.0 (Bodaker et al. 2010).

Ecology and Pathogenesis

Located on the surface of the Dead Sea and other high salt concentration bodies of water, Recombination has genetic information exchanged, mesophilic temperature ranges (BacDive), Ranks as a biosafety risk group level 1 (Admin, 2010)
