Query: NC_012108:5273289 Desulfobacterium autotrophicum HRM2, complete genome
Lineage: Desulfobacterium autotrophicum; Desulfobacterium; Desulfobacteraceae; Desulfobacterales; Proteobacteria; Bacteria
General Information: It was isolated from a marine sediment in the Mediterranean sea near Venice, Italy. It is involved in the anaerobic mineralization of organic matter coming from the water column. Desulfobacterium autotrophicum is capable of growing litho-autotrophically with H2, CO2 and sulfate, but also by coupling sulfate reduction with the oxidation of fatty acids. This organism can transform tetra to dichlormethane.
Subject: NC_010001:434803 Clostridium phytofermentans ISDg, complete genome
Lineage: Lachnoclostridium phytofermentans; Lachnoclostridium; Lachnospiraceae; Clostridiales; Firmicutes; Bacteria
General Information: Isolated from forest soil near the Quabbin Reservoir in Massachusetts, USA. This organism plays an important industrial and ecological role in the anaerobic fermentation of cellulose and produces economically significant levels of acetate and ethanol. 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.
