摘要
采用新型ＤＭＢＡＣ／正庚烷反胶团体系，进行萃取分离提纯α－淀粉酶．考察了表面活性剂浓度、ｐＨ、离子强度、温度等参数对萃取的影响，确定了优化工艺条件，单级萃取α－淀粉酶的总收率可达７８．０％．
The extraction of α-amylaxe by using a reversed micellar phase to transport the enzyme from one aqueous phase to another, has been studied. As a special cationic surfactant DMBAC was used to solutilize α-amylase in heptane and the effects of pH,ionic strength,temperature on the extraction performace and the specific activity of enzyme have also investigated.
