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.

然后，研究固定化酶降解甲基对硫磷，从不同材料的膜载体固定有机磷水解酶的比较中，发现亲水膜比疏水膜适合作固定化酶载体；在此基础上，将有机磷水解酶固定在聚醚砜微滤膜上，并制成酶膜生物反应器，用于降解甲基对硫磷；戊二醛化学交联法固定时，酶液与10%牛血清白蛋白溶液的比例在3：1~2：1，与交联剂的比例在7：2~7：4范围内，固定化效果较好，并发现牛血清白蛋白和膜载体有降低酶活损失的作用；将固定化的酶膜装于酶膜反应器降解甲基对硫磷，实验结果表明：反应器的降解速率与固定化酶量呈正比，也随底物浓度的增加而加快，当流速低时，降解速率随流速增大而加快，到7ml/min以上时，降解速率不随流速脑黾佣洌到獾淖畹团ǘ任？
