Query: NC_009952:592000 Dinoroseobacter shibae DFL 12, complete genome
Lineage: Dinoroseobacter shibae; Dinoroseobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This aerobic anoxygenic phototroph was isolated from cultivated marine dinoflagellates originally from the Bay of Tokyo, Japan. Liquid cultures grown in the dark are distinctly pink, while colonies on complex agar media are dark red.
Subject: 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.
