使用来自Candida cylindracea的尼龙固定化脂肪酶在几乎无水的非极性有机介质己烷中进行长链脂肪酸的酯化。由月桂酸和正丁醇以37 mmol/h的最大初始反应速率生产月桂酸丁酯。当底物以等摩尔量存在，初始浓度为0.5mol/L时，使用非化学计量的底物获得较低的速率。反应速率随温度增加而增加，在35至45°C之间达到最大值，在较高温度下急剧下降。John Wiley & Sons，Inc.
The esterification of a long‐chain fatty acid was conducted using a nylon‐immobilized lipase from Candida cylindracea in a nearly anhydrous, nonpolar organic medium, hexane. Butyl laurate was produced from lauric acid and n‐butanol at a maximum initial reaction rate of 37 mmol/h. g immobilized enzyme when the substrates were present in equimolar amounts at an initial concentration of 0.5 mol/L. Lower rates were obtained using nonstoichiometric amounts of the substrates. The rate of reaction increased with temperature, reaching a maximum between 35 and 45°C and decreasing sharply at higher temperatures. © 1995 John Wiley & Sons, Inc.
