海藻酸钠是一种安全性较高且生产成本较低的材料,淀粉酶在食品工业、造纸业、酒精行业及日化用品等多个领域应用广泛。海藻酸钠由于其生物安全性、良好的成胶成球特性及低廉的生产成本在酶的固定化方面有较广泛的应用。单一淀粉酶对p H及有机溶剂较敏感,高温下不够稳定,在一定程度上限制了其应用。因此,需要对淀粉酶进行固定化以提高其稳定性。将对海藻酸钠固定淀粉酶的进展进行综述并对未来的发展进行展望。 Sodium alginate is a safer and lower cost material. Amylase is widely used in many fields such as food industry, paper industry, alcohol industry and daily chemical industry. Sodium alginate is widely used in enzyme immobilization because of its biological safety, good gelling and ball forming characteristics and low production cost. Single amylase is more sensitive to p H and organic solvents, not stable enough at high temperature, to a certain extent, its application is limited. Therefore, the amylase needs to be immobilized to improve its stability. The progress of the immobilized alginate immobilized amylase will be reviewed and the future development will be forecasted.
