Query: NC_012483:483425 Acidobacterium capsulatum ATCC 51196, complete genome
Lineage: Acidobacterium capsulatum; Acidobacterium; Acidobacteriaceae; Acidobacteriales; Acidobacteria; Bacteria
General Information: Isolated from acidic mine drainage in Yanahara mine, Okayama, Japan. Acidophilic bacterium. This genus comprises a number of species commonly found in water reservoirs, microbial mats, many different soil types, marine and freshwater sediments, as well as in hot-spring mats and sediments, etc. Furthermore, they sometimes form the dominant group in a habitat. These bacteria are involved in the first step of destruction of biologically complex molecules produced by autotrophic (capable of synthesizing their own nutrients) microorganisms. Acidobacterium capsulatum is an aerobic, mesophilic, chemo-organotroph able to use a variety of carbon sources and to grow up to pH 6.0. The species comprises several strains characterized by orange pigmentation, production of menoquinones as their sole quinones, and branched-chain iso fatty acids as their cell envelope components.
Subject: NC_009012:3653111 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.
