  • Lactic acid bacteria with sweetening properties and uses thereof
    Patent number: 11725199
    Abstract: The invention is directed to a lactose-positive, galactose-negative, Streptococcus thermophilus strain releasing glucose during milk fermentation. This Streptococcus thermophilus strain carries mutation in the glcK gene, in the ccpA gene, in the lacZ gene and/or in the ptsH gene, and optionally in one or more genes, in particular one gene, encoding a protein of the mannose-glucose-specific PTS. The invention also concerns a composition comprising at least one, lactose-positive, galactose-negative, Streptococcus thermophilus strain of the invention, and the use of this strain or composition to manufacture a fermented dairy product.
    Type: Grant

    Date of Patent: August 15, 2023
    Assignee: DUPONT NUTRITION BIOSCIENCES APS
    Inventors: Armelle Cochu-Blachere, Christophe Fremaux, Thomas Desfougeres
  • LACTIC ACID BACTERIUM WITH A REDUCTION OF SENSITIVITY TO COS-TYPE BACTERIOPHAGES
    Publication number: 20220117247
    Abstract: The present invention relates to a lactic acid bacterium, in particular a strain of the Streptococcus genus, with reduced sensitivity to cos-type bacteriophages. The invention also relates to methods to engineer these lactic acid bacteria as well as their use to ferment milk.

  • NEW LACTIC ACID BACTERIA
    Publication number: 20220017855
    Abstract: The invention relates to a lactose-positive, galactose-negative, Streptococcus thermophilus strain carrying a mutation in 2 or 3 genes selected from the group consisting of 1) a gene encoding a protein of the mannose-glucose-specific PTS and a glcK gene, 2) a gene encoding a protein of the mannose-glucose-specific PTS and a ccpA gene, and 3) a gene encoding a protein of the mannose-glucose-specific PTS, a glcK gene and a ccpA gene, wherein said strain, when used to ferment milk, provides a low lactose fermented milk and/or a fermented milk not undergoing acidification when stored at fermentation temperature.
