Abstract: |
A process for preparing 1,3-propanediol by adding fumaric acid to activate microns includes preparing culture media, seed culture and fermenting. It features that the fumaric acid is added to the fermentive culture medium for speeding up the utilization of glycerine by bacterial spawn. |
