Fenoxaprop-ethyl was found to be metabolized by a mixed microbial popu
lation isolated from a leachate from a landfill. Fenoxaprop acid and 6
-chloro-2(3H)-benzoxazolone were detected as metabolic products in the
culture broths. It was shown that the microbial population could util
ize fenoxapropethyl as a source of carbon and nitrogen, but the presen
ce of an additional source of carbon increased the metabolism rate.
