<p>The present invention relates to a method for producing α-hydroxy acids from the corresponding α-hydroxy nitrile using a catalyst having nitrilase activity. More specifically, the invention pertains to use of Acidovorax facilis 72W (ATCC 55746) nitrilase to hydrolyze glycolonitrile to glycolic acid, or acetone cyanohydrin to 2-hydroxyisobutyric acid. Glycolonitrile is reacted in an aqueous mixture with a catalyst having Acidovorax facilis 72W nitrilase activity to give glycolic acid selectively, and at high concentration and high yield.-hydroxy nitrile using a catalyst having nitrilase activity.
