Query: NC_008228:2295841 Pseudoalteromonas atlantica T6c, complete genome Lineage: Pseudoalteromonas atlantica; Pseudoalteromonas; Pseudoalteromonadaceae; Alteromonadales; Proteobacteria; Bacteria General Information: Isolated from a biofilm from San Diego Bay in California. Marine biofilm bacterium associated with shell disease in shellfish. A common marine bacterium that exists both in the water column, and in biofilms attached to surfaces. This organism produces a well characterized, commercially important agarase. Pseudoalteromonas atlantica has been isolated from lesions on crabs with shell disease. Shell disease is characterized by progressive degradation of the shell, often leading to an infection of the hemolymph (blood) and may be caused by Pseudoalteromonas, Alteromonas, Vibrio, or other marine organisms. In addition to producing extracellular enzymes which attack the shell, Pseudoalteromonas atlantica produces a the lipopolysaccharide which has been shown to be a potential virulence factor in shell disease.

General Information: This is the type strain for this organism, which was isolated from a hydrothermal vent at a depth of 1300 m from the Lo'ihi Seamount southeast of Hawaii. This organism grows optimally in salt concentrations of 7.5 to 10%. Genome comparison has suggested that the bacterium has maintained its amino acid transport and degradation systems but lost sugar transport and certain sugar metabolic genes suggesting that it lives on amino acids rather than sugars. This may be in keeping with the environment this organism grows in, which is at hydrothermal deep sea vents that are characterized by collections of proteinaceous particles. This organism may colonize these particles by producing exopolysaccharides.
