With Serratia-derived glycerol dehydrogenase; NADH; at 30℃; for 2h;pH 6.5;Aqueous phophate buffer; Enzymatic reaction; (Example 9) Method for synthesizing (S)-3-chloro-1,2-propanediol A Serratia-derived glycerol dehydrogenase solution was obtained from a culture broth of Serratia marcescens IFO12648 strains by a purification operation comprising ammonium sulfate fractionation and ion-exchange chromatography. 1 ml of a 0.1M phosphate buffer (PH 6.5) containing 10 mul of the thus-obtained glycerol dehydrogenase solution, 1.5 mg of 1-chloro-3-hydroxyacetone, and 10 mg of NADH was stirred at 30C for 2 hours.. After the reaction was completed, the reaction solution was saturated with ammonium sulfate, and extracted with an equivalent volume of ethyl acetate.. The amounts of the substrate and product in the extract were measured by gas chromatography (GC) analysis to determine the conversion rate (%).. Also, the optical purity (%ee) of the product was measured by high-performance liquid chromatography (HPLC) analysis after the primary hydroxyl group of the product was tosylated with tosyl chloride.. As a result, (S)-3-chloro-1,2-propanediol was produced with a conversion rate of 100% and an optical purity of 100%ee..
With potassium dihydrogenphosphate; D-glucose; In water; at 30℃; for 24h;pH 5.5;Aqueous phophate buffer; Microbiological reaction; (Example 1) A liquid medium (pH 7.0) containing 4% of glucose, 0.3% of yeast extract, 1.3% of KH2PO4, 0.7% of (NH4)2HPO4, 0.01% of NaCl, 0.08% of MgSO4·7H2O, 0.006% of ZnSO4·7H2O, 0.009% of FeSO4·7H2O, 0.0005% of CuSO4·5H2O, and 0.001% of MnSO4·4-5H2O was prepared, and 5 ml of the liquid medium was injected into each of large test tubes and then sterilized with steam at 120C for 20 minutes. Then, one platinum loop of the microorganisms of each of the genera shown in Table 1 and 2 was inoculated into the liquid medium, and cultured with shaking at 30C for 2 to 3 days. Cells were collected from each of the culture broths by centrifugation, washed with water and then suspended in 1 ml of a 0.1M phosphate buffer (pH 5.5). Then, 0.5 ml of the cell suspension was mixed with 0.5 ml of a 0.1M KH2PO4 aqueous solution containing 5 mg of 1-chloro-3-hydroxyacetone and 20 mg of glucose, and the resultant mixture was placed in a test tube with a stopper and shaken at 30C for 24 hours. After completion of reaction, a saturated amount of ammonium sulfate was added to the reaction solution, and extraction was performed with an equivalent volume of ethyl acetate.

Then, 10 mg of1-chloro-3-hydroxyacetone, 70 mg of NAD+, and 25 mg of glucose were added to 1 ml of the resultant culture broth,and the mixture was then stirred at 30C for 2 hours. After the reaction was completed, the conversion rate and opticalpurity of the reaction product (S)-3-chloro-1,2-propanediol were analyzed by the same method as in Example 9. As aresult, the conversion rate was 42.8%, and the optical purity was 45.8%ee.
