  • Publication number: 20240043790
    Abstract: The invention relates to a method for generating a Streptococcus thermophilus strain exhibiting a “high galactose utilization” profile, which is characterized by a high percentage of consumed galactose at the maximum speed of lactose consumption and optionally a high percentage of consumed galactose at the end of lactose consumption (both as determined by assay I), comprising modifying the sequence of the gal-lac gene cluster. The invention also relates to a Streptococcus thermophilus strain obtained or obtainable by this method, to a Streptococcus thermophilus strain characterized both by the sequence of its gal-lac gene cluster and its “high galactose utilization” profile, to a culture and kit-of part comprising such strains, as well as to the use of such strains in food applications.
