Pentosaceus. These four bacteriocins showed the highest antibacterial activity under acidulous and neutral conditions. The bacteriocin-producing strains inhibited most of related lactic acid bacteria. The bacteriocins produced by strains L. acidophilus Ind-1 and P.

戊糖片球菌产生的细菌素对木瓜蛋白酶敏感，而其它三种细菌素对这种蛋白酶稳定。pH稳定性研究表明，在弱酸性或中性条件下，这些细菌素表现出较高的活性。

Our data indicated that HAI-2 inhibited matriptase activation accompanied with a reduced formation of 130 kDa, activated matriptase/HAI-1 complex. HAI-2 also increased a formation of 70 kDa matriptase/HAI-1 complex.

我们的研究结果显示，HAI-2会经由其第一个Kuniz domain抑制间质蛋白酶的活化，而降低间质蛋白酶与其抑制者HAI-1所形成的130 kDa复合物，并使得另一70 kDa复合物的生成增加。

In this study, different proteases were used to hydrolyze soy protein, and it was found that the amino acid release of the hydrolysis process was related to the type of protease and hydrolyzing time.

利用不同蛋白酶酶解大豆蛋白质，大豆蛋白酶解过程中氨基酸的释放规律表明，氨基酸的释放与蛋白酶的种类和酶解时间有关。

All C.neoformans contain serine protease; Serine proteinase perturbs the integrity of BMEC of the blood-brain barrier, improves open the level of BBB; Secreted serine protease from pathogenic fungi were virulence.

发现新生隐球菌分泌具有活性的胞外蛋白水解酶并含有丝氨酸蛋白酶成分；新生隐球菌自身分泌的丝氨酸蛋白酶可以干扰构成血脑屏障主要成分内皮细胞的完整性使得血脑屏障开放程度提高；致病性真菌分泌的丝氨酸蛋白酶可能是一种毒性因子。

The coagulating effect of the two proteinases and their mixtureon 7S and 11S was compared. Results indicated that two proteinases interacted witheach other during the coagulating process. 11S gel induced by mixture of twoproteinases was more elastic, and 7S gel induced by separated proteinase was moreelastic.

然后采用SP-sepharose阳离子交换剂从木瓜蛋白酶分离出2种蛋白酶组分，对比它们单独作用和复合作用于7S和11S蛋白的促凝能力，结果表明木瓜蛋白酶中两种组分对7S和11S蛋白的促凝过程中存在协同作用，复合作用可以促使11S蛋白形成弹性更强的凝胶，而单独作用可以促使7S蛋白形成弹性更强的凝胶。

Objective To explore the expression of calpain in aging rat cochleas and correlation between change of calpaincalpastatin and agerelated hearing loss.

目的 确定钙蛋白酶在老年聋大鼠耳蜗中的表达和钙蛋白酶－钙蛋白酶抑素平衡变化与老年耳聋的相关性。

Methods Immunohistochemical staining were used to detect the expression and location of calpain in aging rat cochleas, and real time PCR assay were used to detect mRNA level of calpain and calpastatin in cochlear extracts.

采用免疫组织化学染色确定钙蛋白酶在老年大鼠耳蜗中的表达水平和组织定位，采用即时PCR技术分析耳蜗提取物中钙蛋白酶和钙蛋白酶抑素 mRNA水平的变化。

The method of freeze-thawing plus proteinase K plus sonication provided the highest copy number of COWP gene.

冻融法+蛋白酶K法+声裂法提纯隐孢子虫卵囊DNA效果最佳，其次为冻融法+声裂法和蛋白酶K法+声裂法，冻融法+蛋白酶K法效果最差。

The study showed that CH can obviously short- en the fermentation time and enhance the acidification speed.The effect was related to the kinds of the en- zymes.

结果表明，酪蛋白水解物具有明显促进低脂发酵酸奶发酵、缩短发酵时间的作用，中性蛋白酶的促进发酵效果最好，木瓜蛋白酶次之，碱性蛋白酶和胰酶的效果相差不大；各添加样在整个发酵过程中发酵速度都高于空白样，甚至高于双倍接种量的空白样。

The separation purities by new method were determined and compared with those of some traditional methods by SDS-PAGE gradient electrophoresis.

其次，采用中性蛋白酶、碱性蛋白酶等几种常用的蛋白酶对分离的7S和11S球蛋白进行酶解比较实验，发现在相同条件下，7S比11S酶解后的酸溶多肽得率高，7S比11S相对更容易被酶解；通过扫描电镜和SDS-PAGE电泳分析7S和11S的酶解产物，表明7S和11S分子酶解前后的变化明显，但两种大豆蛋白经酶解作用后，均有相当部分未被酶解的蛋白分子残留在酶解残渣中，而酶解离心后的上清液中则已基本不存在原来的蛋白质大分子。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
