after about 50% conversion, this being catalyzed by a protease from Bacillus licheniformis (Alcalase), and subsequent acidic saponification of the recovered ester. Among the methyl, ethyl, octyl, chloroethyl and trichloroethyl esters, the chloroethyl ester exhibited the highest rate of hydrolysis.
通过(+/-)-N-乙酰基-叔胺的酶促水解获得光学纯的D-叔-亮氨酸。亮氨酸氯乙基酯转化率约为50%后,由地衣芽孢杆菌的蛋白酶(Alcalase)催化,随后对回收的酯进行酸性皂化。在甲基,乙基,辛基,氯乙基和三氯乙基酯中,氯乙基酯的水解速率最高。
