A process for producing optically active alcohols having high optical purity by using an optical resolution catalyst comprising immobilized water-soluble proteins extracted from inexpensive and safe cereals or beans, and enzymatically converting feedstock substrates (optionally acylated racemic alcohols, ketones, etc.) therewith optionally followed by hydrolysis. This process aims at solving the problems encountered in the conventional processes for producing optically active alcohols by using microbial cells, enzymes originating in microorganisms, enzymes originating in animal tissues or cultured plant cells, for example, low yield due to side reactions, undesirable effects on ecological systems and an increase in cost associating therewith, and problems in the reaction processes, such as needs for septic operations and prolonged subculture.
一种利用光学分解催化剂生产高光学纯度光学活性醇的工艺,该催化剂由从廉价安全的谷物或豆类中提取的固定化水溶性蛋白质组成,并通过酶转化原料底物(可选择酰化外消旋醇、酮等),然后进行水解。该工艺旨在解决使用微生物细胞、微生物酶、动物组织酶或植物细胞培养酶生产光学活性醇的传统工艺中遇到的问题,例如,副反应导致的低产量、对生态系统的不良影响和随之而来的成本增加,以及反应过程中的问题,如需要化粪池操作和长时间的亚培养。
