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.

Subject: NC_011059:2233993 Prosthecochloris aestuarii DSM 271, complete genome

Lineage: Prosthecochloris aestuarii; Prosthecochloris; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria

General Information: This species is a green sulfur bacterium which forms sedimentary biofilm layers. It has been shown to be associated with coral killed by Black-Band Disease (BBD) a microbial infection of larger coral species. This is a concern for reef conservationists as the larger species are responsible for coral scaffolds, and their reduction by disease would have considerable impact on the reef structure. While there is currently no cause-and-effect link between Prosthecochloris aestuarii and BBD, the species was found on coral which was killed by the disease and was not found on healthy coral or in the surrounding seawater.
