In this study, Novozym 435, a lipase B from Candida antarctica, was used for fatty acid polymerization. For the first time, an apolar reaction media, n-hexane, was used to synthesize in vitro estolides from trans-hydroxy-fatty acids derived from the biotransformation of oleic acid by Pseudomonas aeruginosa 42A2 NCIMB 40045. We studied the effects of the substrate, the enzyme ratio, the enzyme stability
在这项研究中,Novozym 435,一种来自南极念珠菌的脂肪酶 B,用于脂肪酸聚合。首次使用非极性反应介质正己烷从铜绿假单胞菌 42A2 NCIMB 40045 生物转化油酸后衍生的反式羟基脂肪酸合成体外 estolides。我们研究了底物的影响,酶比例、酶稳定性和生物催化剂的可重复使用性。为了确定形成的低聚物的结构,使用液相色谱质谱法和 MALDI-TOF 质谱法,其中 DHB 基质用氢氧化锂中和,以获得更简单的质谱。以30%的反应收率合成了由(10S)-HOME的两个单元组成的Estolides。最后筛选出各种脂肪酶,另一种非极性有机溶剂异辛烷,
