海藻糖酶

The degradation of trehalose into smaller molecules such as glucose or fructose under the catalysis of trehalase is the biochemical base of the germination of aquatic microsporidian spores .

内部渗透压的升高是微孢子虫孢子发芽的直接驱动力，海藻糖酶催化海藻糖水解为葡萄糖或果糖是水生型微孢子虫孢子发芽的生化基础，p H值、离子种类及浓度、温度、射线等均能影响孢子发芽。

When Nosema bombycis infected silkworm, the activity of midgut trehalase decreased significantly, which is mainly due to formation of large quantities of schizonts.

Nosema bombycis感染家蚕后，家蚕中肠海藻糖酶活性显著下降，大量裂殖体的形成是其下降的重要原因。

At the optimal condition, the amount of decrement and time form liner relationship and acidic trehalase activity is 338.6mg/.

在此条件下，海藻糖的消耗量与时间成线性关系，并得出该菌的酸性海藻糖酶活性为338.6mg/。

This method can be used in ensuring acidic trehalase activity of baker's yeast and can also be used in selective breeding of freeze-tolerant baker's yeast.

可用于面包酵母酸性海藻糖酶活性的测定和耐冷冻酵母菌株的选育。

The developer, trehalase amount, trehalose amount, reaction time and temperature, solvent were discussed. Validoxylamine test showed that the method of trehalase-inhibit in vitro is reliable for screening.

离体测试模型主要涉及溶剂的选择、显色剂选择、反应的温度和时间、海藻糖酶和海藻糖的用量等内容，所建立的离体测试模型用井岗霉素验证了该方法的可靠性。

Validamycins have been one of the most popular and economical biopesticides in China, by microbial transformation of which validoxylamine A and valienamine can be produced. Validoxylamine A has strong inhibition on trehalase and it is a new promising insecticide. Valienamine demonstrates strong glucosidase inhibitory activity, which can also be used as intermediate in the synthesis of medicines for diabetes.

井冈霉素目前已成为我国最经济最受欢迎的生物农药之一，用微生物转化法分解井冈霉素可以得到井冈霉亚基胺A和井冈胺，前者对海藻糖酶有强烈的抑制作用，有望开发成为新型生物杀虫剂，而后者是一种糖苷酶抑制剂，也可作为合成降糖药的原料。

We use 0.5% CMC to preserve the activity of Metarhizium anisopliae at room temperature. Then we carry on the RT-PCR semi-quantitative examination of the trehalase. The fresh Metarhizium anisopliae not preserved do control.

对用0.5%的羧甲基纤维素钠室温保存五个周的绿僵菌，进行海藻糖酶的半定量RT-PCR检测，用没有经过处理的固体培养基上培养14天的绿僵菌做对照。

The result discovered that the trehalase expression of the Metarhizium anisopliae preserved reaches the maximum value the third day to drop afterward with the same trends of un preserved.

结果发现，经过保存的绿僵菌，其海藻糖酶的表达趋势和未保存的基本一致，第三天达最大值随后表达量下降。

Trehalase plays an important role in glycogen accumulation in the formarion of diapaused eggs. At the beginning of diapause, glycogen phosphorylase is the key enzyme to glycogen decomposition and the formation of sorbitol and glycerol, whereas at the stage of diapause termination, NAD-sorbitol dehydrogenase is the key enzyme to sorbitol decomposition and glycogen re-synthesis.

在滞育卵形成过程中，海藻糖酶对糖原的积累起着重要的作用；在滞育开始时，糖原的分解与山梨醇、甘油的形成，糖原磷酸化酶是关键酶；在滞育解除时，山梨醇的分解与糖原的再生成时山梨醇脱氢酶(NAD-sorbito1 dehydrogenase)是关键酶。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
