Abstract A number of bacteria and yeast was screened for asymmetric reduction of prochiral chloroacetone into chiral 1-chloro-2-propanol, which is chemically convertible into chiral 1,2-epoxypropane. In this way Rhodotorula glutinis produced optically pure S-1,2-epoxypropane with 98% enantiomeric excess and in a relatively high final concentration. The enzyme that catalysed the asymmetric reduction was an NAD(P)H-dependent alcohol dehydrogenase. Reduction of racemic 3-chloro-2-butanone resulted in mixtures of cis and trans-2,3-epoxybutane, indicating that no enantioselective reduction of this haloketone occurred.
