Enantioselective oxidation of racemic 1,2-propanediol to D-(-)-actic acid by Gluconobacter oxydans
Tetrabedron: Asmmetry 15(2004)1275-1277，-0001，（）：
Ghiconobacter oxydans DSM 2003 was firstly used in the production of (R)-2-hydroxy-proionic acid through microbial oxidation of recemic 1,2-propanediol. The biotransformation was processed with high enantionmeric excess (＞99%) and near theoretical lyicld (48% of racemic 1,2-propanediol) when the substrate concentration was lower than 20g/L. When the substrate concentration was increased. maintaining the pH at 6.0 helped to improve the enantionselectivity.
