摘　　要：以壳聚糖为载体 ,戊二醛为交联剂制得的固定化AS 1 398中性蛋白酶。对其pH稳定性、热稳定性和操作稳定性进行了研究。其结果表明 ,酶被固定化后 。The stabilities of both AS 1 398 natural and immobilized neutral proteases to pH,heat,store shelf life and operation using life were studied in comparison with their enzymetic activities.The results showed that these stabilities were greatly enhanced when the AS 1 398 neutral protease was immobilized on the carrier.

关 键 词：壳聚糖 固定化酶 中性蛋白酶 制备 水解明胶
