摘　　要：采用DM-130大孔树脂为载体，对脂肪酶进行了固定化，研究了固定化条件对催化活性的影响，得到了最佳固定化条件：温度为45℃，pH值为8.0，吸附时间为6h，载体与脂肪酶的质量比为30：1。This paper describes the immobilization of lipase with DM-130 macroporous resin as a carrier. The effecring factors of immobilization on the catalytic activity of lipase are studied ,and the optimal immobilization conditions are obtained. The optimal temperature is 45 ℃, pH value is 8.0 and the time for absorption is 6 h ;the ratio of support to lipase is 30.
