Query: NC_014623:7482229 Stigmatella aurantiaca DW4/3-1 chromosome, complete genome
Lineage: Stigmatella aurantiaca; Stigmatella; Cystobacteraceae; Myxococcales; Proteobacteria; Bacteria
General Information: Social gliding soil bacterium. Stigmatella aurantica, commonly isolated from rotting wood and bark, is a member of a group of organisms called myxobacteria. These organisms have a complex development and differentiation life cycle. 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. Stigmatella aurantica produces a number of compounds, such as aurafuron A and stigmatellin, which may be important as anti-cancer agents.
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.
