Query: NC_012856:207194 Ralstonia pickettii 12D chromosome 1, complete genome
Lineage: Ralstonia pickettii; Ralstonia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: Isolation: Copper-contaminated sediment from a lake; Country: USA; Temp: Mesophile; Habitat: Fresh water, Host, Soil. Ralstonia pickettii can be isolated from a wide range of environmental and clinical samples. This species is a nocosomial pathogen. It is associated with infections caused by contaminated solutions, such as distilled water and intravenous solutions. Ralstonia pickettii strains resistant to heavy metals have also been isolated from heavy metal contaminated environments.
Subject: NC_011420:2803196 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.
