Abstract
The present invention provides a method for enzymatically producing optically active mandelic acid derivatives. An optically active mandelic acid derivative (shown as Formula II) is produced by reacting a culture or cell body of a microorganism, or processed products thereof, with a phenylglyoxylic acid derivative, and then recovering the obtained optically active mandelic acid derivative, wherein the microorganism has the ability to stereo-selectively reduce the phenylglyoxylic acid derivative. An optically active mandelic acid obtained according to the present invention is useful as an intermediate for the synthesis of pharmaceuticals and agricultural chemicals.
