Lineage: Fibrobacter succinogenes; Fibrobacter; Fibrobacteraceae; Fibrobacterales; Fibrobacteres; Bacteria

General Information: Temp: Mesophile; Temp: 37C; Habitat: Host. Cellulolytic rumen bacterium. This bacterium is one of the three most predominant cellulolytic organisms in the rumen. Since cellulose is one of the most abundant carbohydrates on the planet, this organism is, therefore, an important part of the global carbon biogeochemical cycle, converting the mass of fixed carbon generated by photosynthetic organisms back to products that eventually end up as carbon dioxide. Increasing cellulose degradation is an important goal in industrial processes. This organism is highly specialized for cellulose degradation, and is only capable of utilizing cellulose and cellulolytic degradation products as carbon sources. Access to cellulose is a rate-liming step in degradation, and the cellulolytic organisms have devised a number of mechanisms for improving access to this insoluble substrate, one of which is the production of surface-localized cellulases. The active enzymes are cell wall associated, but the presence of cellulosomes, large multiprotein cellulase complexes, has not been detected in this organism. Adherence is another method used to promote cellulose degradation, and this organism produces an extracellular matrix of glycoprotein glycocalyx which allows attachment to insoluble cellulose.

Subject: NC_014974:404015 Thermus scotoductus SA-01 chromosome, complete genome

Lineage: Thermus scotoductus; Thermus; Thermaceae; Thermales; Deinococcus-Thermus; Bacteria

General Information: This is a thermophilic, facultatively mixotrophic sulfur-oxidizing bacterium. Thermus scotoductus SA-01 was isolated from fissure water in a South African gold mine. This organism is a thermophilic bacterium which was isolated from fissure water in the Witwatersrand Supergroup at a depth of 3.2 km below surface in a South African gold mine. It is a 2.9-billion-year-old formation of low permeability sandstone and shale with minor volcanic units and conglomerates. The ambient temperature of the rock is approximately 60°C. Samples were collected from a freshly mined rock surface and from a water-producing borehole that penetrated 121 m horizontally into the formation at a depth of 3,198 m. T. scotoductus SA-01 is a facultative anaerobe capable of coupling the oxidation of organic substrates to reduction of a wide range of electron acceptors, including nitrate, Fe(III), Mn(IV) or S(0) as terminal electron acceptors.
