Query: NC_011060:330437 Pelodictyon phaeoclathratiforme BU-1, complete genome
Lineage: Pelodictyon phaeoclathratiforme; Pelodictyon; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria
General Information: Pelodictyon phaeoclathratiformeBU-1 was isolated from lake water in 1989. This organism is a phototrophic green sulfur bacteria that inhabits hydrogen sulfide-containing water and freshwater mud, brackish waters and marine environments. This organism forms net-like microcolonies and contains gas vescicles. It is believed that the gas vesicles provide the buoyancy necessary to keep the cell at the optimal depth for photosynthesis.
Subject: NC_011420:69843 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.
