A microorganism or a preparation thereof is permitted to act on a mixture of enantiomers of an epoxide such as 3-chlorostyrene oxide and the product optically active epoxide is recovered. The microorganism able to produce an optically active (S)-epoxide from the mixture of enantiomers of the epoxide include, for example, a microorganism strain belonging to the genus Candida, the genus Rhodosporidium, the genus Rhodococcus and the genus Nosardioides. Examples of the microorganism capable of producing an optically active (R)-epoxide from said mixture include a microorganism strain belonging to the genus Trichosporon, the genus Geotrichum, the genus Corynebacterium, the genus Micrococcus and the genus Brevibacterium. The objective optically active epoxide can efficiently be obtained with ease and simplicity from the corresponding mixture of enantiomers of the epoxide.
允许微生物或其制剂作用于环氧化物(如 3-氯苯乙烯氧化物)的对映体混合物,并回收光学活性环氧化物产品。能够从环氧化物的对映体混合物中产生光学活性(S)-环氧化物的微生物包括,例如,属于白色念珠菌属、Rhodosporidium 属、Rhodococcus 属和 Nosardioides 属的微生物菌株。能够从所述混合物中产生光学活性(R)-环氧化物的微生物菌株的例子包括属于三孢菌属、革囊菌属、高丽杆菌属、微球菌属和布雷维杆菌属的微生物菌株。从相应的环氧化物对映体混合物中可以高效、简便地获得具有光学活性的环氧化物。
