Query: NC_015259:624979 Polymorphum gilvum SL003B-26A1 chromosome, complete genome Lineage: Polymorphum gilvum; Polymorphum; ; ; Proteobacteria; Bacteria General Information: Polymorphum gilvum SL003B-26A1 is a type strain of a newly published novel species in the novel genus Polymorphum. It was isolated from a crude oil-polluted saline soil in Shengli Oilfield, China and could use the crude oil as the sole carbon source. Oil pollution has become a global issue because of its severe ecological impact and destruction. Bioremediation is proved to be an effective process to restore the oil polluted environments. The complete genome sequence of Polymorphum gilvum SL003B-26A1 provides new strategies for bioremediation of oil contaminated environment.

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.
