General description
2-Chlorobenzoic acid degradation by pure cultures of Burkholderia cepacia strain with and without the bacterial hemoglobin gene was studied in parallel membrane bioreactors. Intramolecular hydrogen atom tunneling in 2-chlorobenzoic acid has been studied by low-temperature matrix-isolation infrared spectroscopy.
Application
2-Chlorobenzoic acid was used to study the degradation of 2-bromobenzoic acid by Pseudomonas aeruginosa.

A strain of Pseudomonas aeruginosa producing 2-bromobenzoic acid, designated 2-BBZA, was isolated by enrichment culture from municipal sewage. It degraded all four 2-halobenzoates as well as certain 3-halo- and dihalobenzoates, though none of the 4-halobenzoates supported growth of this organism.

The microbial populations in PCB-contaminated electric power substation capacitor bank soil (TVA soil) and from another PCB-contaminated site (New England soil) were compared to determine their potential to degrade PCB. Known biphenyl operon genes were used as gene probes in

TfdT is a LysR-type transcriptional regulator that activates the transcription of the chlorocatechol degradative gene operon tfdCDEF of the chlorobenzoate-degrading bacterium Burkholderia sp. NK8. To identify the amino acids involved in the effector recognition by TfdT, a polymerase-chain-reaction-based random mutagenesis

A study was made of the metabolic and co-metabolic intermediates of 2- and 3-chlorobenzoate, 2,3- and 3,5-dichlorobenzoate to elucidate the mechanism(s) involved in the negative effects observed on the growth of a chlorobenzoate-degrading microbial consortium in the presence of mixed

We have identified in Pseudomonas aeruginosa strain JB2 a novel cluster of mobile genes encoding degradation of hydroxy- and halo-aromatic compounds. Nineteen open reading frames were located and, based on sequence similarities, were putatively identified as encoding a ring hydroxylating
