Query: NC_007575:1694877 Sulfurimonas denitrificans DSM 1251, complete genome
Lineage: Sulfurimonas denitrificans; Sulfurimonas; Helicobacteraceae; Campylobacterales; Proteobacteria; Bacteria
General Information: This organsim is a sulfur-oxidizing bacterium isolated isolated from estuarine mud in the Netherlands. Sulfur-oxidizing bacterium. Sulfurimonas denitrificans, formerly Thiomicrospira denitrificans, is a denitrifying chemolithoautotroph that uses sulfide or thiosulfate and nitrate or nitrite as the electron donor and acceptor. This organism has been identified in hydrothermal vent areas and from oilfields and may play a role in the cycling of sulfur in these environments.
Subject: NC_021182:93000 Clostridium pasteurianum BC1, complete genome
Lineage: Clostridium pasteurianum; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria
General Information: Environment: Soil; Isolation: Coal-cleaning residues; Temp: Mesophile; Temp: 30C. 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. Known opportunistic toxin-producing pathogens in animals and humans. Some species are capable of producing organic solvents (acetone, ethanol, etc,), molecular hydrogen and other useful compounds. Clostridium pasteurianum was first isolated from soil by the Russian microbiologist Sergey Winogradsky. This organism is able to fix nitrogen and oxidize hydrogen into protons. The genes involved in nitrogen fixation and hydrogen oxidation have been extensively studied in this organism.
