Description générale

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 metabolic fate of [14C]-labelled 2 and 4-chlorobenzoic acids (2- and 4-CBA) has been determined in the rat following intraperitoneal (i.p.) administration at 100 mg/kg to male rats. The major route of elimination for both 2-and 4-CBA was urine with

The potential for real-time PCR (RTm-PCR) detection of the genetically engineered strain Pseudomonas putida GN2 was studied during 2-chlorobenzoate (2-CB) degradation in three different soils. The strain contained the constructed plasmid pGN2 which encoded genes for 2-CB oxidation (cbdA) and

Protein mass spectrometry and molecular cloning techniques were used to identify and characterize mobile o-halobenzoate oxygenase genes in Pseudomonas aeruginosa strain JB2 and Pseudomonas huttiensis strain D1. Proteins induced in strains JB2 and D1 by growth on 2-chlorobenzoate (2-CBa) were

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
