In the present work, diazinon pesticide which is known as nondegradable and neurotoxic material was removed by organophosphorus hydrolase (OPH). 25? culture temperature and addition of 0.2 mM ethylenediamine tetraacetate were optimal conditions for the OPH production in Escherichia coli. 25 and 50 mg/L diazinon were treated efficiently with all over 90% removal efficiencies using cell lysates through ultrasonication process. Thus, a novel method developed in this work could be applied to the bioremediation technology in the contaminated region with high diazinon concentration.
