| 摘 要： | 通过金属离子对纤维素酶系中3大组分（β-葡萄糖苷酶、内切葡聚糖酶和外切葡聚糖酶）酶活的影响，探讨金属离子对纤维素酶活影响的作用机理。试验结果表明，金属离子Co2＋、Zn2＋、Mn2＋对内切葡聚糖酶酶活具有促进作用；Co2＋和K＋对外切葡聚糖酶的酶活具有促进作用；Co2＋、Mn2＋、Ca2＋和Mg2＋对β-葡萄糖苷酶具有促进作用，来源不同的纤维素酶，因其酶系组分不一样，酶促离子对纤维素酶的促进作用有所差异。

| Abstract: | The study of the three major components （ β- glucosidase, endo - 1,4 - 3 - D - glucanase and exo - 1,4 - β-D -glucanase） enzyme activity was influenced by the metal ions. The results showed that Co2＋ , Zn2 ＋ , Mn2＋ were promoted to internal endoglucanase activity, Co2 ＋ and K ＋ were promoted to External endoglucanase activity, Co2 ＋ , Mn2 ＋ , Ca2 ＋ and Mg2 ＋ were enhanced the β- glucosidase activity. Because of its different component, the activity of enzymes cellulose from different sources was found to be dissimilar under the same metal ions concentration. |
