【摘要】 分别以醋酸纤维素TiO2膜(AC.TiO2膜)、羧甲基纤维TiO2膜(CMC.TiO2膜)和聚丙烯TiO2膜(PP.TiO2膜)为载体吸附固定糖化酶,并与醋酸纤维素、羧甲基纤维素和聚丙烯固定糖化酶的性能进行了比较,得出以AC.TiO2膜和PP.TiO2膜对糖化酶的吸附性能及稳定性能均较好,PP.TiO2膜固定的糖化酶使用8次后其剩余酶活仍能保持在72%。更多还原

【Abstract】 The absorption properties for glucoamylase on TiO₂-coated acetyl cellulose,carboxymethyl cellulose and polypropylene were studied respectively.Meanwhile the control experiment was also proceeded.The acetyl cellulose TiO₂ film and polypropylene TiO₂ film showed better for glucoamylase absorption, and this immobilized glucoamylase also had higher stability.The residual activity of glucoamylase immobilized on polypropylene TiO₂ film could maintain 72% after being used eight times.更多还原
