Bioremediation using enzymes has become an attractive approach for removing hazardous chemicals
such as organophosphate pesticides from the environment. Enzymes immobilized on solid carriers are
particularly suited for such applications. In this study, the organophosphate degrading enzyme A (OpdA)
was covalently immobilized on highly porous nonwoven polyester fabrics for organophosphate pesticide
degradation. The fabrics were first activated with ethylenediamine to introduce free amine groups, and
the enzyme was then attached using the bifunctional crosslinker glutaraldehyde.
