Query: NC_013410:1285857 Fibrobacter succinogenes subsp. succinogenes S85 chromosome,

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_012881:478042 Desulfovibrio salexigens DSM 2638, complete genome

Lineage: Desulfovibrio salexigens; Desulfovibrio; Desulfovibrionaceae; Desulfovibrionales; Proteobacteria; Bacteria

General Information: Isolation: mud in British Guyana; Temp: Mesophile; Temp: 37 C; Habitat: Mud. Desulfovibrio are sulfate-reducing bacteria which reduce sulfate to sulfide found in soil, freshwater, saltwater and the intestinal tract of animals. These organisms typically grow anaerobically, although some can tolerate oxygen, and they utilize a wide variety of electron acceptors, including sulfate, sulfur, nitrate, and nitrite, as well as others. A number of toxic metals are reduced, including uranium (VI), chromium (VI) and iron (III), making these organisms of interest as bioremediators. These organisms are responsible for the production of poisonous hydrogen sulfide gas in marine sediments and in terrestrial environments such as drilling sites for petroleum products.
