| 摘 要： | 应用二环己基羰二亚胺活化海藻酸钠,然后与纤维素酶相联接.修饰后纤维素酶的性质发生了变化.其中,最适温度、最适pH均发生了变化;对pH、热稳定性有了较大程度的增强;对某些抑制剂(Hg~(2 )、Cu~(2 )、Ag~ 、Ca~(2 ))有较强的抵抗能力.

| Abstract: | The cellulase was modified by linking to sodium alginate chemically. Asa result of the modification, the properties of the enzyme, such as the optimum temper-ature and pH, etc have changed. The stability to heat has strenthened to a more extentand it had stronger resistances to some inhibitors(e. g. Hg~(2 ), Cu~(2 ), Ag~ ,Ca~(2 )). |
