Dicamba ((3,6-dichloro-2-metoxybenzoic acid) Degradation By Pseudomonas maltophilia

By: Musa SARI
Dicamba (3,6-dichloro-2-metoxybenzoic acid) is a herbicide which is used to treat broadleaf vegetation. Dicamba is used by Pseudomonas maltophilia as a sole source of carbon and energy. The goal of this study was to quantitate dicamba degrading activity in concentrated whole cells of P. maltophilia. Pseudomonas maltophilia. can degrade dicamba at 30 centigrade. It was found that concentrated exponentionally grown cells degrade dicamba at a great rate. Dicamba degradation is measured in washed cells harvested from exponential phases of growth. Dicamba degradation was shown to occur in three kinetic phases.
