General description
脂肪酶属于水解酶类。基于动、植物的微生物主要产生脂肪酶。也可由海洋生物生产。
我们致力于为您提供更环保的替代产品，以符合“绿色化学的12项原则”的一项或多项原则要求。该产品针对生物柴油研究进行了优化，可提高能效并防止浪费。有关详细信息，请参阅《Biofiles》的文章。
脂肪酶由一种经过基因改性的黑曲霉（ Aspergillus niger ）微生物进行深层发酵并吸附在大孔树脂上而制成。
Application
脂肪酶丙烯酸树脂用于：
- 作为催化剂，用丁酸进行pLACT的酯化反应
- 作为添加剂，用于全氢化菜籽油（FHCO）和高油酸葵花籽油（HOSO）混合物，进行酶促酯交换
- 研究其对酯化时油酸转化程度的影响
热稳定脂肪酶固定化制剂，特别适用于酯和酰胺的合成，并具有广泛的底物特异性。
Biochem/physiol Actions
脂肪酶可用于洗涤剂、食品、皮革、制药和乳品行业。它具有多种特性，例如底物特异性、立体特异性和区域选择性。还参与多种生物转化反应，例如水解、酯化、酸解和氨解。由于因为可用于酯化、水解、氨解和酯交换反应，南极假丝酵母（Candida antarctica ）脂肪酶B被认为是一种重要的酶。
Other Notes
对于相同反应，本品可重复使用。不同反应则不建议重复使用，因为会有交叉污染风险，且活性也可能降低。可重复次数尚未确定。

Enzymatic ring-opening polymerization (ROP) is a benign method for preparing polyesters, such as polylactides and other polylactones. These reactions are typically carried out at relatively high temperatures (60-130 °C), however, there is a deficiency of enzyme-compatible solvents for such thermally-demanding
