Description and significance
Pseudoaltermonas haloplanktis is a curve, rod shaped (0.2 to 1.5 by 1.8 to 3 µm), Antarctica psychrophile bacterium that is composed mainly in ~40% DNA G + C content (Gauthier et al). It was initially called Alteromonas tetraodonis, but has been reclassified as Alteromonas haloplanktis then to Pseudoalteromonas haloplanktis from Phylogenetic assay (Gauthier et al). In addition, Pseudoaltermonas haloplanktis is a Gram negative bacterium that is non-spore-forming, not luminescent, and is motile by polar flagella. This organism was isolated from the Antartica sea water and is found to grow only in marine environment at 20ºC. Researchers have sequenced some of its genome such as DNA Ligase and cellulase to give an understanding of how its enzymatic proteins allow it to adapt at such low temperature.
