Query: NC_009481:1523764 Synechococcus sp. WH 7803 chromosome, complete genome
Lineage: Synechococcus; Synechococcus; Synechococcaceae; Chroococcales; Cyanobacteria; Bacteria
General Information: Marine Synechococcus and Prochlorococcus are the most abundant photosynthetic organisms on earth and between them account for about half of the world's photosynthesis. WH7803 was isolated from the Sargasso Sea, in mesotrophic water (rich in nutrient salts) and is the best physiologically characterized marine Synechococcus strain.
Subject: NC_003030:1 Clostridium acetobutylicum ATCC 824, complete genome
Lineage: Clostridium acetobutylicum; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria
General Information: This strain was isolated in 1924 from garden soil in Connecticut, USA, by E. Wyer and L. Rettger. It is one of the best studied solventogenic clostridia. Solvent-producing 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. This organism is a benign saccharolytic and proteolytic soil bacterium capable of producing a number of organic solvents (solventogenic bacterium) through fermentation of various organic compounds. acetobutyricum were isolated by Chaim Weizman during the World War I and used to develop industrial starch-based acetone, butanol and ethanol fermentation processes.
