We have investigated the Suzuki cross-coupling reaction of aryl bromides at low catalyst loading and low temperature.

经过一系列实验条件的摸索，采取了在比较低的催化剂用量和比较低的温度的实验条件下进行了一系列底物的Suzuki偶联反应，结果以极好的收率得到相应的偶联产物。

In this study, we isolate, purify and characterize endo-β-glucanase by Ascomycete Xylaria regalis. The cellulose-containing medium is used to induce the production of the cellulose-degrading enzymes. When these enzymes are produced at maximum level, we harvest and filtrate the culture medium. The filtrate is purified by anion exchanger column and hydrophobic interaction column (phenyl-650M). The purification fold of endo-β- glucanase increases 4.3 times, the specific activity approaches 3.7 unit/mg, and the recovery is 27.6%, respectively.

为了分离且纯化此株菌产生在培养基中的endo-β-glucanase，先将此菌在cellulose液态培养基中大量培养，在此酵素达到最高峰时，利用滤纸过滤将菌丝及菌液分开，收集粗酵素液，再经过阴离子交换树脂及疏水性层析管柱(Phenyl-650M)等步骤予以纯化，所得到最终酵素纯度为 4.3倍，比活性为3.7 unit/mg，回收率为27.6%。

The 2008 Beijing Olympic Games, asdic also catch this wave, the Beijing Olympic opening ceremony that night after a home appliance store to see inside a lot of people did not know looking at what went in I realized that the opening ceremony of the Beijing Olympic Games performance, when the saw the show full of surprise, standing inside a station is a quick one hour, until reading the Chinese Taipei team played returned home.

这次2008北京奥运，asdic也搭上这波浪潮，北京奥运开幕式那天晚上经过了家电卖场看到里面好多人，也不知道在看什麼，走进去才发现原来是北京奥运开幕式的表演，当时看到那个表演满惊讶的，站在里头一站就是快一小时，直到看完中华队出场才回家。

Because sterility testing is a very exacting procedure, where asepsis of the procedure must be ensured for a correct interpretation of results, it is important that personnel be properly trained and qualified.
