4-Chlorosalicylate (4-CS) can be degraded completely by a bacterial consortium consisting of Pseudomonas reinekei (MT1), Achromobacter spanius (MT3) and Pseudomonas veronii (MT4). The fourth species Wautersiella falsenii (MT2) is thought to act as a 'necrotizer' of the community. Single cell

Pseudomonas sp. strain MT1 is capable of degrading 4- and 5-chlorosalicylates via 4-chlorocatechol, 3-chloromuconate, and maleylacetate by a novel pathway. 3-Chloromuconate is transformed by muconate cycloisomerase of MT1 into protoanemonin, a dominant reaction product, as previously shown for other muconate
