Processes for production of optically active 3-phenyl-1,3-propanediol by asymmetric assimilation
First Claim
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.

Abstract
A microorganism or a preparation thereof is permitted to act on a mixture of enantiomers of 3-phenyl-1, 3-propanediol, and the residual optically active 3-phenyl-1,3-propanediol is harvested.
The genera of those microorganisms which are able to leave (R)-3-phenyl-1,3-propanediol include Candida, Hansenula, Rhodotorula, Protaminobacter, Aspergillus, Alternaria, Macrophomina, Preussia and Talaromyces.
The genera of those microorganisms which are able to leave (S)-3-phenyl-1,3-propanediol include Candida, Geotrichum, Leucosporidium, Pichia, Torulaspora, Trichosporon, Escherichia, Micrococcus, Corynebacterium, Gordona, Rhodococcus, Aspergillus, Emericella, Absidia, Fusarium, Dactylium, Serratia and Pseudomonas.
