Properties of an immobilized pesticide-hydrolyzing enzyme.


A bacterial enzyme(s) capable of hydrolyzing nine organophosphate insecticides was covalently bound to glass. The efficiency of this binding reaction ranged from 4 to 17%. Under continuous column operation, the immobilized enzyme(s) had an extrapolated half-life of 280 days. The specific activity of this glass-covalently bound hydrolase activity for… (More)
