Query: NC_008148:2156873 Rubrobacter xylanophilus DSM 9941, complete genome Lineage: Rubrobacter xylanophilus; Rubrobacter; Rubrobacteraceae; Rubrobacterales; Actinobacteria; Bacteria General Information: Cellulose-degrading bacterium. This genus contains two species: Rubrobacter radiotolerans and Rubrobacter xylanophilus. These two species represent the oldest lineage (deepest branch) of the Actinobacteria and are distantly related to Mycobacteria and Streptomycetes. Both species are thermophilic and exhibit high tolerance to radiation. Very little research has been done on these organisms and little is known other than their taxonomic characterization. Rubrobacter xylanophilus was isolated from a thermally polluted industrial runoff in the United Kingdom. Some strains of this species are capable of degrading hemicellulose and xylan (polymers of plant origin), and could play a significant role in the degradation of these compounds in the wood and paper industry as well as in the environment.

General Information: This strain was isolated from sediment contaminated with cis-dichloroethane (cDCE), a common pollutant resulting from widespread manufacture and use of industrial solvents. This bacterium is the only known organism capable of using cDCE as a sole carbon and energy source. The ability of this strain to convert ethene to epoxyethane suggests that the first step in the cDCE biodegradation pathway is the oxidation of cDCE to an epoxide compound. Bacteria that are able to grow on cDCE are rare, and have only been found in very few highly selective artificial environments. The discovery of this bacteria may provide a low cost, self-sustaining bioremediation method in areas where cDCE is a problem contaminant.
