Popis:	Two mixed bacterial cultures were isolated from a French soil adapted to the dicarboximide fungicide vinclozolin. The vinclozolin was transformed by the mixed bacterial cultures according to two degradation pathways: (a) the formation of 2-[[(3,5-dichlorophenyl)carbamoyl]oxy]-2-methyl-3-butenoic acid and then 3,5-dichloroaniline or (b) the formation of 3‘,5‘-dichloro-2-hydroxy-2-methylbut-3-enanilide and then 3,5-dichloroaniline. The structure of 2-[[(3,5-dichlorophenyl)carbamoyl]oxy]-2-methyl-3-butenoic acid was unambiguously established by 1H and 13C 2-D NMR analysis. A bacterial strain isolated from soil that degrades this compound was identified as a strain of Corynebacterium sp. Attempts to obtain pure vinclozolin-degrading strains via 3‘,5‘-dichloro-2-hydroxy-2-methylbut-3-enanilide were unsuccessful. Keywords: Vinclozolin; fungicide-degrading bacteria; chemical transformation
