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.

Subject: NC_008095:7499255 Myxococcus xanthus DK 1622, complete genome

Lineage: Myxococcus xanthus; Myxococcus; Myxococcaceae; Myxococcales; Proteobacteria; Bacteria

General Information: First isolated from soil in 1941. Bacterium with a multi-stage lifecycle. M.xanthus is a Gram-negative rod-shaped bacterium. This organism undergoes a complex development and differentiation pathway. When cell density increases, the organism switches to "social motility" where aggregates of cells can gather together into masses termed fruiting bodies that may consist of up to 100 000 cells. This organism is also utilized industrially to produce the anticancer drug epithilone.
