1. A process for increasing the optical purity of (R)-3-phenyl-1,3-propanediol comprising:

  • providing a mixture of (R) and (S) enantiomers of 3-phenyl-1,3-propanediol,subjecting said mixture to a microorganism selected from the group consisting of Candida lambica, Hanesnula minuta, Rhodotorula rubra, Protaminobacter ruber, Aspergillus niger, Aspergillus ficuum, Alternaria kiduchiana, Macrophomina phaseoli, Preussia terricola, and Talaromyces flavus var. flavus, or a preparatus derived therefrom, that is capable of selectively utilizing the (S)-3-phenyl-1,3-propanediol enantiomer, andrecovering the residual, optically active 3-phenyl-1,3-propanediol.
