Description 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. Packaging 100 g in poly bottle 5 g in glass bottle 500 g in glass bottle
