Query: NC_009767:2051203 Roseiflexus castenholzii DSM 13941, complete genome Lineage: Roseiflexus castenholzii; Roseiflexus; Chloroflexaceae; Chloroflexales; Chloroflexi; Bacteria General Information: Photosynthetic thermophile. Roseiflexus castenholzii is related to the Chloroflexaceae, a family of anoxygenic phototrophs. However, it differs from other members of that family in that it lacks chlorosomes and bacteriochlorophyll-c. Bacteriochlorophyll-a is the major photosynthetic pigment in Roseiflexus castenholzii. This organism was isolated from a hot spring microbial mat in a Japanese hot spring.

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.
