Query: NC_012560:2906459 Azotobacter vinelandii DJ, complete genome

Lineage: Azotobacter vinelandii; Azotobacter; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria

General Information: This organism was first isolated from the soil in Vineland, New Jersey, although it is found worldwide. It is a large obligate aerobe that has one of the highest respiratory rates of any organism. Azotobacter vinelandii also produces a number of unusual nitrogenases which allow it to fix atmospheric nitrogen to ammonia, a compound it can then use as a nitrogen source. It protects the oxygen-sensitive nitrogenase enzymes through its high respiratory rate, which sequesters the nitrogenase complexes in an anoxic environment. This organism has a number of unusual characteristics. Under extreme environmental conditions, the cell will produce a cyst that is resistant to dessication and is surrounded by two capsular polysaccharide layers. This organism produces two industrially important polysaccharides, poly-beta-hydroxybutyrate (PHB) and alginate. PHB is a thermoplastic biopolymer, and alginate is used in the food industry. Alginate is also used by the pathogen Pseudomonas aeruginosa to infect the lungs of cystic fibrosis patients.

Subject: NC_010682:2642269 Ralstonia pickettii 12J chromosome 1, complete sequence

Lineage: Ralstonia pickettii; Ralstonia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria

General Information: Ralstonia pickettii 12J was isolated from copper-contaminated sediment from a lake in Michigan, USA. In addition to being highly resistant to copper, strain 12J is also resistant to zinc and cadmium. Ralstonia pickettii can be isolated from a wide range of environmental and clinical samples. This species is a nocosomial pathogen. It is associated with infections caused by contaminated solutions, such as distilled water and intravenous solutions. Ralstonia pickettii strains resistant to heavy metals have also been isolated from heavy metal contaminated environments.
