Abstract: | p-Chlorophenyl methylcarbamate (PCMC) underwent spontaneous hydrolysis in aqueous solution to p-chlorophenol with concomitant loss of ability to inhibit hydrolysis of the phenylcarbamate isopropyl phenylcarbamate (propham). A phenylcarbamate-degrading soil Arthrobacter sp. had no direct effect on PCMC itself but formed 4-chlorocatechol during the metabolism of p-chlorophenol. |
