Degradation of chlorosubstituted aromatic compounds by Pseudomonas sp. strain B13: fate of 3,5-dichlorocatechol

Abstract

The degradation of 3,5-dichlorocatechol by enzymes of 3-chlorobenzoate-grown cells of Pseudomonas sp. strain B13 was studied. The following compounds were formed from 3,5-dichlorocatechol: trans-2-chloro-4-carboxymethylenebut-2-en-4-olide, cis-2-chloro-4-carboxymethylenebut-2-en-4-olide, and chloroacetylacrylate as the decarboxylation product of 2-chloromaleylacetate. They were identified by chromatographic and spectroscopic methods (UV, MS, PMR). An enzyme activity converting trans-2-chloro-4-carboxymethylenebut-2-en-4-olide into the cis-isomer was observed.
