摘要： The favorable microbes for the asymmetric reduction of prochiral aromatic ketones was isolated from soil using acetophenone as the sole carbon source, when the asymmetric reduction of acetophenone (ACP) to chiral ?-phenethyl alcohol (PEA) was chosen as the model reaction. Two microbe strains with excellent catalytic activity were obtained. They were and identified by bacteria identification. The product of the asymmetric reduction of ACP catalyzed by was mainly R-PEA and that by was mainly S-PEA. The yield and enantiomeric excesses (e.e.) could respectively reach 75% and 90% for , and 80% and 70% for , much higher than those catalyzed by baker s yeast.
