Query: NC_015930:1397524 Lactococcus garvieae ATCC 49156, complete genome
Lineage: Lactococcus garvieae; Lactococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: Lactococcus garviae is responsible for mastitis in cows and buffalos, and it has been isolated from clinical specimens of human blood, urine, and skin. Lactococcus garvieae is also a well recognized bacterial fish pathogen. L. garvieae as the etiological agent of a hemorrhagic septicemia in farmed trout that was characterized by bilateral exophthalmos, darkening of the skin, congestion of the intestine, liver, kidney, spleen, and brain.
Subject: NC_012560:4311906 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.
