The result of immobilization showed that hydrophile membranes were more advantageous than hydrophobe ones to act as immobilization carrier. Crosslinking organophosphorus hydrolase by glutaraldehyde on polyethersulfone membrane is a simple and practical immobilization method. An appropriate amount of bovine serum albumin and crosslinker is necessary to get a good result of immobilization. In the biodegradation of methyl-parathion through enzyme membrane reactor, the effect of immobilized enzyme amount, flow rate of peristaltic pump, pH of the feed, and the methyl-parathion concentration on biodegradation rate was studied. It was shown that the biodegradation rate increased with immobilized enzyme amount and substrate concentration. Biodegradation rate didn't increase when the folw rate of the peristaltic pump was larger than 7 ml/min.
