Rhizopus japonicus demethylates the herbicides monuron, fluometuron, and monolinuron into the metabolites 3-(p-chlorophenyl)-1-methylurea (V), 3-(m-trifluormethylphenyl)-1-methylurea (VI), and 3-(p-chlorophenyl)-1-methoxyurea (VII), respectively. Buturon loses its N-(1-methyl-2-propynyl) group to give compound V. These metabolites, which were identified by nuclear magnetic resonance and mass spectrometric analysis accumulate after a 1-wk growth.
