Query: NC_007948:4176579 Polaromonas sp. JS666, complete genome
Lineage: Polaromonas; Polaromonas; Comamonadaceae; Burkholderiales; Proteobacteria; Bacteria
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.
Subject: NC_007348:2115152 Ralstonia eutropha JMP134 chromosome 2, complete sequence
Lineage: Cupriavidus pinatubonensis; Cupriavidus; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: This organism is found in both soil and water and has great potential for use in bioremediation as it is capable of degrading a large list of pollutants including chlorinated aromatic compounds. The bacterium can utilize hydrogen, carbon dioxide, as well as organic compounds for growth and is a model organism for hydrogen oxidation as it can grow on hydrogen as the sole energy source. It was originally isolated due to its ability to degrade the herbicide 2,4-dichlorophenoxyacetic acid, which is due to the degradative functions being encoded on a plasmid (pJP4). Metabolically versatile bacterium. Cupriavidus necator also known as Ralstonia eutropha is a soil bacterium with diverse metabolic abilities. Strains of this organism are resistant to high levels of copper or are able to degrade chloroaromatic compounds such as halobenzoates and nitrophenols making them useful for bioremediation.
