Abstract (2. Language): 
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 oC. 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.

Abstract (Original Language): 
Dicamba (3,6-dikloro-2-metoksibenzoik asit ) geniş yapraklı bitkileri kontrol etmek için kullanılan bir herbisittir. Dicamba, Pseudomonas maltophilia tarafından bir enerji kaynağı olarak kullanılır. Bu çalışmanın amacı, P. maltophilia tarafından metabolize edilen dicamba yı ölçmekti. Pseudommonas maltophilia 30 C de dicambayi metabolize edebilmektedir. Exponent olarak büyüyen P. maltophilia hücrelerinin dicamba yı büyük bir oranda metabolize ettikleri saptandı. Dicamba metabolize hızı exponenet olarak büyütülen hücreler kullanılarak ölçüldü. Dicamba nın metaboloize olması 3 kinetik faz tarafından sağlandığı saptandı.
