| 摘要 |
The present invention concerns a new method for the production of 1,3- propanediol comprising culturing a microorganism on a culture medium with high glycerine content. The invention also concerns a new microorganism, or strain of microorganism, adapted for the production of 1,3-propanediol from medium comprising high glycerine content. The invention also concerns an "adapted microorganism" which glycerol metabolism is directed to 1,3-propanediol production, and which is allowed to grow in the presence of a high concentration of industrial glycerine. The invention also concerns a biosourced 1,3-propanediol obtained by the process thereof. Finally the invention concerns the use of the above described biosourced 1,3- propanediol as extender chain in thermoplastic polyurethane, as monomers in polytrimethylene terephtalate and as a component in cosmetics formulations. |
