Abstract
Crude extracts of Pseudomonas sp. grown on 4-chloro-2-methylphenoxyacetate as sole source of carbon were shown to oxidize 4-chloro-2-methylphenoxyacetate to 5-chloro-o-cresol and glyoxylate. A labelled 2,4-dinitrophenylhydrazone was isolated from an incubation mixture in which 4-chloro-2-methylphenoxy[carboxy-(14)C]acetate was used. The hydrazone was shown to behave identically on thin-layer chromatograms with the authentic 2,4-dinitrophenylhydrazone of glyoxylate. Radioactivity assay showed that 82% of the side chain of 4-chloro-2-methylphenoxyacetate was recovered as glyoxylate.
