Query: NC_011420:365505 Rhodospirillum centenum SW, complete genome Lineage: Rhodospirillum centenum; Rhodospirillum; Rhodospirillaceae; Rhodospirillales; Proteobacteria; Bacteria General Information: Rhodospirillum centenum, also called Rhodocista centenaria, is a nitrogen-fixing photoheterotroph with a complex life cycle. R. centenum is one of the few known thermotolerant purple bacteria species with optimal growth temperature of 44 dgrees C and a maximal growth temperature of 48 degrees C. In liquid media this organism is motile by a single polar flagellum. R. centenum produces lateral flagella to become a swarming cell. Under low nutrient conditions R. centenum forms a desiccation- and UV-resistant cyst. R. centenum can often be cultivated from hot springs such as those found at Yellowstone National Park. R. centenum is emerging as a model organism for genetic and molecular genetic analysis of cyst formation.

General Information: This strain was isolated from a sample of coastal sea water near a French Antarctic station. This organism is adapted to growth at low temperatures and reactive oxygen species by a number of putative dioxygenases and fatty acid desaturases amongst other proteins. The organism can grow optimally in salt concentrations of 1.5 to 3.5% NaCl.The genome consists of 2 chromosomes, one of which may replicate unidirectionally. Some interesting features of this genome include the lack of the nucleoid-associated gene hns, a lack of genes involved in molybdopterin metabolism, a lack of the cAMP-CAP complex, and a lack of the PEP-dependent PTS system.
