A new isolate of Pseudomonas stutzeri that degrades 2-chloronitrobenzene

A strain of Pseudomonas stutzeri ZWLR2-1 was isolated from soil contaminated with chloronitrobenzenes and identified by 16S rDNA sequencing. This bacterium released chloride and nitrite into the medium when grown on 0.5 mM 2-chloronitrobenzene. PCR amplification and DNA sequencing revealed a DNA fragment encoding a polypeptide homologous to the alpha-subunit of ring-hydroxylating dioxygenases.
