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.

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

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

Application of Vitreoscilla hemoglobin (VHb) technology to 2-CBA degradation by Burkholderia cepacia strain DNT under hypoxic conditions was studied in continuous culture chemostats. Dechlorination abilities of both recombinant (VHb gene (vgb) containing) and untransformed cells were investigated at various dilution
A S Yuroff et al.

We investigated the mechanisms of uptake of 2-chlorobenzoate (2-CBa) and 2-hydroxybenzoate (2-HBa) by Pseudomonas huttiensis strain D1. Uptake was monitored by assaying intracellular accumulation of 2-[UL-ring-14C]CBa and 2-[UL-ring-14C]HBa. Uptake of 2-CBa showed substrate saturation kinetics with an apparent Km of
