It is an object of the present invention to provide an inexpensive and efficient industrial method for obtaining (S)-2-pentanol, (S)-2-hexanol, 1-methylalkyl malonic acid and 3-methyl carboxylic acid at a high optical purity. The present invention provides a method of producing (S)-2-pentanol or (S)-2-hexanol which comprises allowing certain types of microorganisms or transformed cells, a product obtained by treating said microorganisms or cells, a culture solution of said microorganisms or cells, and/or a crude purified product or purified product of a carbonyl reductase fraction obtained from said microorganisms or cells, to act on 2-pentanone or 2-hexanone.
本发明的目的是提供一种廉价高效的工业方法,用于高光学纯度地获得(S)-
2-戊醇、(S)-
2-己醇、1-甲基烷基
丙二酸和3-甲基
羧酸。本发明提供了一种生产(S)-
2-戊醇或(S)-
2-己醇的方法,其包括让某些类型的微
生物或转化细胞、经处理后得到的产物、上述微
生物或细胞的培养液,和/或从上述微
生物或细胞中获得的羰基还原酶分数的粗提纯产物或纯化产物作用于
2-戊酮或
2-己酮。
