PROBLEM TO BE SOLVED: To provide a method for producing S-1,2-propanediol by the use of a microorganism, by which the S-1,2-propanediol having a high optical purity can be produced from an enantiomer mixture of 1,2-propanediol by a low cost and technically simple method using the microorganism. SOLUTION: This method for producing the S-1,2-propanediol by the use of the microorganism comprises culturing the microorganism belonging to Acetobacteraceae and capable of consuming R-1,2-propanediol as a single carbon source or its cultured cells in a culture medium containing an enantiomer mixture of 1,2-propanediol as a single carbon source to degrade the R-1,2-propanediol, and then collecting the left S-1,2-propanediol from the cultured liquid, or treating the enantiomer mixture of 1,2-propanediol with the microorganism belonging to Acetobacteraceae and having an ability to act on the enantiomer mixture of the 1,2-propanediol to leave the S-1,2-propanediol, the culture cells, or their treated product, and then collecting the left S-1,2-propanediol.
