葡萄糖氧化酶

葡萄糖氧化酶用途

葡萄糖氧化酶在食品和饮料工业中用作防腐剂和稳定剂,通常来源于真菌黑曲霉。葡萄糖氧化酶能与细胞内的葡萄糖和氧气(O2)反应生成过氧化氢(H2O2)和葡萄糖酸,切断癌细胞的营养来源,从而抑制癌细胞的增殖[1][2][3]。

[体外研究]

葡萄糖氧化酶是氧化还原酶的一个子类,对电子从氧化剂转移到还原剂进行催化。葡萄糖氧化酶利用氧作为外部电子受体,释放过氧化氢(H2 O2)。葡萄糖氧化酶在商业加工中有许多应用,包括改善颜色和味道,增加食物材料的持久性,去除干鸡蛋中的葡萄糖,以及消除不同果汁和饮料中的氧气[4]。

葡萄糖氧化酶制备

1.由黑曲霉变种(Aspergillus niger var.)受控培养而得。

2.以废糖蜜、KH2PO4、NaNO3等为培养基，用青霉菌No．778进行深层培养，可产生显著量的胞外葡萄糖氧化酶。

3.以黑曲霉和表属菌株为生产菌，采用深层通风培养方法制得培养液，然后经透析、柱层析、硫酸铵分级沉淀得产中。
