Query: NC_006371:1997954 Photobacterium profundum SS9 chromosome 2, complete sequence
Lineage: Photobacterium profundum; Photobacterium; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria
General Information: Isolated at a depth of 2500 m from the Sulu Trough. High pressure tolerant bacterium. This bioluminescent genus was originally identified in 1878 in association with hake (a marine fish) in Cape Town, South Africa. This species was originally isolated from an amphipod homogenate enrichment from the Sulu Sea. It is a genetically tractable model system for studies of low temperature and high pressure adaptation, and has been used in studies of mono- and polyunsaturated fatty acid production under these conditions.

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.
