Characterization of potential Pseudomonas Isolates capable of degrading chlrobenzoates

Twelve sewage and soil isolates belonging to genus Pseudomonas were screened for their ability to degrade and dechlorinate 2-chlorobenzoic acid (2-CBA), 3-chlorobenzoic acid (3-CBA) and 2,4-chlorobenzoic acid (2,4-DCBA). On the basis of growth of the isolates of three chlorobenzoates and their subsequent dechlorination rate, an aerobic Pseudomonas strain PNK-3 was selected for the study.
