Abstract
Optically active 1,3-BUTANEDIOL is produced by contacting microorganisms selected from respective groups of specific genuses having an effect of acting on an enantiomeric mixture of 1,3-butanediols and leaving (R)-1,3-butanediol or (S)-1,3-butanediol in enantiomeric mixture, and collecting the remaining optically active (R)-1,3-butandiol or (S)-1,3-butanediol. Optically active 1,3-butanediol can be produced by an economically excellent and convenient means.
Claims7
A process for producing an optically active 1,3-butanediol, comprising treating an enantiomeric mixture of 1,3-butanediols with a microorganism selected from the group consisting of Aciculoconidium aculeatum, Brettanomyces anomalus, Cochliobolus miyabeanus, Corynespora cassiicola, Dactylium dentroides, Echinopodospora jamaicensis, Hamigera avellanea, Helminthosporium sigmoideum, Nectria cinnabarina, and Phialocephala bactrospora, and which is capable of catabolizing (S)-1,3-butanediol in said enantiomeric mixture of 1,3-butanediols, and recovering optically active (R)-1,3-butanediol.
A process for producing an optically active 1,3-butanediol, comprising treating an enantiomeric mixture of 1,3-butanediols with a microorganism selected from the group consisting of Ambrosiozyma monospora, Ambrosiozyma philentoma, Bordetella bronchiseptica, Fusarium oxysporum, Fusarium solani, Gibberella fujikoroi, Glomerella cingulata, Gonatobotryum apiculatum, Neosartorya fischeri, Oospora astringenes, Paecilomyces variotti, Preussia terricola, Spetoria glycines, Talaromyces flavus, and Westerdykella multispora, and which is capable of catabolizing (R)-1,3-butanediol from said enantiomeric mixture of 1,3-butanediol, and recovering (S)-1,3-butanediol.
