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.
1-22. (canceled)
A method for the production of 1,3-propanediol in a continuous fermentation process of glycerine, comprising culturing a producing microorganism on a culture medium, said producing microorganism allowing the conversion of glycerol into 1,3-propanediol, and recovering the 1,3-propanediol, wherein the culture medium comprises a high concentration of industrial glycerine, said industrial glycerine comprising glycerol, and wherein the producing microorganism is a microorganism previously adapted to grow in the presence of a high concentration of industrial glycerine.
A method for the modification of a microorganism into a microorganism adapted to grow in the presence of a high concentration of industrial glycerine, comprising culturing the microorganism on a culture medium comprising high concentration of industrial glycerine at a low dilution rate and selecting the adapted microorganism able to grow on the culture medium having high concentration of industrial glycerine.
A microorganism adapted to grow in the presence of a high concentration of industrial glycerine, susceptible to be obtained by a method comprising culturing the microorganism on a culture medium comprising high concentration of industrial glycerine at a low dilution rate and selecting the adapted microorganism able to grow on the culture medium having high concentration of industrial glycerine.
