Query: NC_009511:2921448 Sphingomonas wittichii RW1 chromosome, complete genome
Lineage: Sphingomonas wittichii; Sphingomonas; Sphingomonadaceae; Sphingomonadales; Proteobacteria; Bacteria
General Information: Sphingomonas wittichii was isolated from water from the Elbe River in Germany. This organism is able to grow using dibenzo-p-dioxin or dibenzofuran as a sole carbon source. These compounds are widespread environmental contaminants formed as by-products in the manufacture of pesticides and paper, and during the incineration of industrial waste. The enzymes involved in degradation of these substrates is contained, in part, on plasmids in Sphingomonas wittichii.
Subject: NC_007347:3204637 Ralstonia eutropha JMP134 chromosome 1, 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.
