produced from ricinoleic acid ((9Z,12R)‐12‐hydroxyoctadec‐9‐enoic acid) by a fatty acid double bond hydratase, into (R)‐3‐hydroxynonanoic acid, 9‐hydroxynonanoic acid, and 1,9‐nonanedioic acid with a high conversion yield of ca. 70%. The biotransformation was driven by enzyme/whole‐cell biocatalysts, consisting of the esterase of Pseudomonas fluorescens and the recombinant Escherichia coli expressing the
已经研究了可再生长链脂肪酸到工业上相关的C9羧酸的区域特异性氧基官能化。一个例子是由脂肪酸双键水合酶将蓖麻油酸((9 Z,12 R)-12-羟基十八碳9-9烯酸)生产的10,12-二羟基十八碳烯酸生物催化转化为(R)- 3-羟基壬酸,9-羟基壬酸和1,9-壬二酸,转化率高。70%。生物转化是由酶/全细胞生物催化剂驱动的,该酶由荧光假单胞菌的酯酶和表达黄斑微球菌仲醇脱氢酶的重组大肠杆菌组成。,恶臭假单胞菌KT2440的Baeyer-Villiger单加氧酶和不动杆菌属的伯醇/醛脱氢酶。NCIMB9871。在20 U / g具有不溶性反应物的干细胞中,高转化率和高产物形成速率表明,各种(多羟基)脂肪酸可通过同时进行的酶/整个细胞生物转化而转化为多功能产品。这项研究将有助于疏水物质的基于酶的功能化。
