| Research Abstract |
This study developed an enzyme-immobilized membrane mitigating biofouling in a membrane bioreactor for wastewater treatment. Radiation-induced graft polymerization was employed to graft polymer chain with subsequent introduction of a functional group with high hydrophilicity onto a polyethylene microfiltration membrane. The introduction of the functional group successfully maintained hydrophilicity as high as the pristine membrane. This modified membrane further immobilized an enzyme allowing for degradation of quorum-sensing compounds which trigger biofilm formation. Biofilm formation of Agrobacterium tumefaciens, which mediates the quorum-sensing compounds, was significantly reduced by the membrane.
