Query: NC_014833:3268102 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_009012:3204696 Clostridium thermocellum ATCC 27405, complete genome
Lineage: Clostridium thermocellum; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria
General Information: This strain is a well studied producer of endoglucanase and several restriction endonucleases. Thermophilic cellulose degrading bacterium. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA. Some species are capable of producing organic solvents (acetone, ethanol, etc,), molecular hydrogen and other useful compounds. This organism is a thermophilic anaerobe that produces an extracellular enzyme system capable of degrading crystalline cellulose to soluble sugars that are further utilized as the carbon source for growth.
