  • Microorganism and method for improved 1,3-propanediol production by fermentation on a culture medium with high glycerine content
    Patent number: 11655486
    Abstract: The present invention concerns a new method for the production of 1,3-propanediol comprising culturing a recombinant microorganism converting glycerol into 1,3-propanediol and overexpressing the hcpR and/or frdX gene on a medium comprising glycerine. A recombinant microorganism for the production of 1,3 propanediol from glycerol, wherein said microorganism converts glycerol into 1,3-propanediol and 10 overexpresses the hcpR and/or the frdX gene.

  • Microbial consortium for 1,3-propanediol production using high glycerol concentration
    Patent number: 10982237
    Abstract: The present invention relates to a microbial consortium, especially adapted for growth and production of 1,3-propanediol from a culture medium with high glycerinecontent and specifically with a high concentration of industrial glycerine. More particularly, this microbial consortium comprises at least one strain C. acetobutylicum and at least one strain chosen among strains of C. sporogenes and/or strains of C. sphenoides. The invention also relates to a method for the production of 1,3-propanediol by culturing this microbial consortium resulting in a co-culture of these particular different microorganisms.
