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_010556:2773396 Exiguobacterium sibiricum 255-15, complete genome
Lineage: Exiguobacterium sibiricum; Exiguobacterium; Bacillales Family XII; Bacillales; Firmicutes; Bacteria
General Information: This organism was isolated from a 2-3 million-year permafrost core in Siberia, Russia and can survive and grow rapidly at low temperatures. Analysis of long-term survival of psychrophilic organisms such as this one may aid understanding of the potential growth of organisms in astrobiology. Exiguobacterium sibiricum is a psychrotolerant organism able to grow at temperatures that range from -6 to 40 degrees C. This organism is also able to survive repeated freeze/thaw cycles which may contribute to its ability to survive in cold environments.
