Query: NC_009511:187508 Sphingomonas wittichii RW1 chromosome, complete genome
Lineage: Sphingomonas wittichii; Sphingomonas; Sphingomonadaceae; Sphingomonadales; Proteobacteria; Bacteria
General Information: Sphingomonas wittichii was isolated from water from the Elbe River in Germany. This organism is able to grow using dibenzo-p-dioxin or dibenzofuran as a sole carbon source. These compounds are widespread environmental contaminants formed as by-products in the manufacture of pesticides and paper, and during the incineration of industrial waste. The enzymes involved in degradation of these substrates is contained, in part, on plasmids in Sphingomonas wittichii.
Subject: NC_008228:372520 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.
