查询词典 biocatalyst

Since C6 and higher alcohols are not obtainable by a direct biochemical route, it is proposed to synthesize these using known chemical reactions, wherein the raw material for synthesis is biogas and lower C2-C5 alcohols obtained by the inventive method wherein the amino acids leucine, isoleucine, and valine, or a mixture thereof, optionally obtained from yeast autolysate, is used as a biocatalyst at the stage of fermentation.

因为C6和更高级醇类不能通过直接生物化学途径制得，所以提出用已知的化学反应合成这些化合物，其中合成的原料为本发明方法制得的生物气和C2-C5醇类，其中任选从酵母自溶作用得到的亮氨酸、异亮氨酸和缬氨酸或其混合物的氨基酸在发酵阶段用作生物催化剂。

Stereoselectivity is the key affecting whether a biocatalyst can be effectively applied to chiral synthesis.

立体选择性是生物催化剂能否有效地应用于手性合成的关键。

As a biocatalyst, free enzyme's defect can't meet with the requirement of modern industry. So it's important to develop a new kind of material which can immobilize the free enzyme efficiently.

酶是一种生物催化剂，游离酶存在的缺点已经不能适应现代工业生产的需要，固定化材料的选择是固定化酶研究的重点。

Once an active biocatalyst has been constructed, it usually will require significant improvement to be of practical value (i.e., perform at economically defined conditions).

一旦某一活跃的生物催化剂建造起来之后，它通常需要有意义的改进来实现其实际价值（即在从经济学的角度所定义的条件下来实现）。

Enzyme is a kind of biocatalyst which can catalyze chemical reaction with the most specific, the highest efficien...

酶是自然界中存在的一种最为专一、效率最高、反应最为迅速，并能在常温下进行催化的生物催化剂。

This paper focuses on the stability study of Rhizopus oryzae IFO4697 when used for the methanolysis of renewable oils for biodiesel production. The results showed that water content was important for achieving high catalytic activity and good stability of the biocatalyst. The optimum water content was found to be 5%-15%. Both particle size and desiccation methods showed no obvious effect on the stability of the biocatalyst. With GA cross-linking pretreatment, the stability of the biocatalyst could be improved significantly. When Rhizopus oryzae IFO4697 repeatedly used for next batch reaction, direct vacuum filtration was found to be a good way for the maintenance of good stability of the biocatalyst.

本实验对固定化全细胞Rhizopus oryzae IFO4697催化植物油脂合成生物柴油的稳定性进行了系统地研究，结果表明：反应体系水含量对于全细胞催化剂的反应活性和催化稳定性有重要影响， 5%~15%含水量适宜；研究范围内，载体粒度及干燥方式对稳定性影响不显著；经过戊二醛交联后，全细胞催化油脂甲醇解反应的稳定性显著提高， 1200 h反应后，仍然可以保持75%的生物柴油得率；真空抽滤直接回用的方式有利于稳定性的保持。
