実験手順

To 50 ml of a culture solution of E. coli HB101 (pNTCMG1) prepared in the same manner as in Example 6, 5 g of glucose, 6 mg of NADP, 4 g of 2-chloro-1-(3′-chlorophenyl)ethanone and 4 g of toluene were added. The mixture was stirred at 30° C. for 24 hours while adjusting the pH of the mixture to 6.5 by adding 5 M sodium hydroxide dropwise. After completion of the reaction, the reaction solution was extracted with toluene. The solvent was removed and then an extracted material was analyzed. As a result, (R)-2-chloro-1-(3′-chlorophenyl)ethanol having an optical purity of 82.0% e.e. was obtained in a yield of 90.5%.
