Query: NC_010376:186510 Finegoldia magna ATCC 29328, complete genome
Lineage: Finegoldia magna; Finegoldia; Clostridiales Family XI; Clostridiales; Firmicutes; Bacteria
General Information: It is isolated most frequently from various infection sites, including soft tissue, bone and joint, and diabetic foot infections. This species, formerly Peptostreptococcus magnus, is a commensal bacterium colonizing human skin and mucous membranes. It has been shown to cause valve endocarditic in humans. Gram-positive anaerobic cocci (GPAC) are a major part of the normal human flora colonizing skin and mucous membranes of the mouth and gastrointestinal tracts. In GPAC, Finegoldia magna (formerly Peptostreptococcus magnus) has the highest pathogenicity and is isolated most frequently from various infection sites, including soft tissue, bone and joint, and diabetic foot infections.
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.
