Abstract

Biodegradation of the organophosphorus insecticide monocrotophos by a local strain of Penicillium corylophilum has been confirmed to be via the production of a thermolabile extracellular oxidizing enzyme. The enzyme is active over a relatively wide range of pH values (6-9) with an optimum activity at pH 8.0. Moreover, the possibility of using the partially purified enzyme as field inoculum to decontaminate soil from monocrotophos residues was also studied.
