Abstract

A microbiological process for the oxidation of methyl groups in aromatic 5- or 6-member ring heterocycles to the corresponding carboxylic acid. The heterocycle serves as the substrate and exhibits no substituent on the carbon atoms adjacent to the methyl groups to be oxidized. The reaction of the heterocycle takes place by means of microorganisms of the genus Pseudomonas utilizing toluene, xylene, or cymene. The enzymes of the microorganisms have been previously induced.
