  • Publication number: 20190010521
    Abstract: 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.

  • Publication number: 20180355390
    Abstract: A method can produce L-methionine and/or a derivative of L-methionine. The method includes: culturing a microorganism for the fermentative production of L-methionine and/or a L-methionine derivative in a culture medium comprising a carbon source, a sulphur source and nitrogen source to produce L-methionine and/or a L-methionine derivative; recovering the L-methionine or L-methionine derivative obtained from the culturing; adding an alcohol solvent or acetonitrile to the L-methionine and/or the L-methionine derivative thereof containing fraction obtained from the recovering to precipitate the L-methionine and/or L-methionine derivative; and recovering L-methionine and/or L-methionine derivative.
