Query: NC_014833:3667748 Ruminococcus albus 7 chromosome, complete genome
Lineage: Ruminococcus albus; Ruminococcus; Ruminococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: Environment: Host; Temp: Mesophile; Temp: 40C. The bacterium requires phenylacetic and phenylpropionic acids for maximal growth. The organism produces cellulosomes at the cell surface that are multimeric protein complexes that contain scaffolding proteins and degradative enzymes. Understanding the metabolism of plant polysaccharides may enable scientists to improve the productivity of ruminant organisms such as cattle
Subject: NC_011420:3822765 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.
