Metabolism of 4‐chlorophenol by Azotobacter sp. GP1: Structure of the meta cleavage product of 4‐chlorocatechol

A mutant strain of Azobacter sp. GP1 converted 4‐chlorphenol to 4‐chlorocatechol under cometabolic conditions. Under the same conditions the wild‐type strain accumulated yellow compound, which by chemical and spectroscopic methods was identified as 5‐chloro‐2‐hydroxy‐6‐oxohexadienoic acid (5‐chloro‐...

Description
Summary:A mutant strain of Azobacter sp. GP1 converted 4‐chlorphenol to 4‐chlorocatechol under cometabolic conditions. Under the same conditions the wild‐type strain accumulated yellow compound, which by chemical and spectroscopic methods was identified as 5‐chloro‐2‐hydroxy‐6‐oxohexadienoic acid (5‐chloro‐2‐hydroxy‐muconic semialdehyde). The structure of this compound indicates a meta‐proximal cleavage of 4‐chlorocatechol.
