<p>A method for producing optically active cyanohydrins, comprising adding recombinant microorganism cells which have been transformed by introducing an hydroxynitrile lyase enzyme gene and which retain the activity of the enzyme, to a reaction system comprising a reaction solvent containing aldehydes or ketones, and hydrogen cyanide or a substance capable of producing cyanide ion in the reaction system. According to the present invention, optically active cyanohydrins can easily and efficiently be synthesized by using the recombinant cells themselves without the need for extracting hydroxynitrile lyase therefrom.</p> |
