摘要
α-半乳糖苷酶催化α-半乳糖苷键的水解,可将豆制食品及饲料中的抗营养因子α-半乳糖苷类转化分解,改善营养成分使其易于消化吸收。近年,α-半乳糖苷酶的固定化更是成为研究的热点。作为固定化酶技术的重要组成部分,载体及固定化方法的选取在很大程度上直接影响着固定化酶的活性及稳定性。综述了近些年国内外有关α-半乳糖苷酶固定化方法、固定化载体材料的研究现状和发展趋势,以期对固定化α-半乳糖苷酶的酶活性及稳定性提高提供参考。
α- galactosides catalyzes the hydrolysis of α- galactosidic linkage,it is advantageous to decompose α- galactosides( an anti- nutritional factor) in soybean foods and feeds for improving soybean's nutrition composition and promoting assimilation. As an important part of the immobilization,the selection of the carrier material and the immobilization method directly affect the activity and stability of the immobilized enzyme. Recent research progress of the immobilization method and carrier materials for the immobilized α- galactosides were reviewed in order to provide reference for further research on activity and stability of the immobilized α- galactosides.
