肠Ⅱ的麦芽糖酶、蔗糖酶、乳糖酶、 海藻 糖酶和纤维二糖酶等5种二糖酶活性均显著高于肠Ⅰ和肠Ⅲ（P<0.05）。

Therefore it is very necessary to delete or decrease the activity of acid and neutral trehalase in the yeast in order to increased trehalose production .

因此，为了提高海藻糖的产量，从该菌株中去除或降低酸性和中性 海藻 糖酶活力是必要的。

In addition trehalase activity and trehalose content were also affected by virus but they played different roles in tripartite interactions .

另外， 烟 粉虱 体内 海藻 糖酶活性与海藻糖含量分别受到病毒不同方式的影响， 表明它们在三者互作中具有不同的作用。
