Query: NC_008254:2728693 Mesorhizobium sp. BNC1, complete genome
Lineage: Chelativorans; Chelativorans; Phyllobacteriaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This organism was isolated from a mixed-culture enriched from sewage using the chelating agent EDTA (binds divalent cations - ethylenediamine tetraacetic acid) as the sole carbon and nitrogen source. EDTA is often found at toxic waste sites where it is bound to metals and radionuclides, which affects bioremediation efforts. This bacterium is capable of EDTA degradation by itself.
Subject: NC_008782:401667 Acidovorax sp. JS42, complete genome
Lineage: Acidovorax; Acidovorax; Comamonadaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: Acidovorax sp. JS42, formerly Pseudomonas sp. JS42, was isolated from nitrobenzene-contaminated sediment and is capable of using 2-nitrotolulene as a sole carbon and energy source. 2-nitrotolulene, a nitroaromatic compound, is used in the manufacture of dyes, pigments and explosives. Nitroaromatic compounds, which contain an aromatic ring with one or more nitro groups attached, are a significant contaminant in industrial soils. Acidovorax sp. JS42 degrades 2-nitrotolulene by first removing the nitro moiety producing 3-methylcatechol. The enzyme involved in this process, 2-nitrotolulene dioxygenase, has been purified and characterized.
