摘要： The present invention relates to a Streptococcus thermophilus strain, wherein the strain is galactose-fermenting, wherein the strain carries a mutation in the DNA sequence of the glcK gene encoding a glucokinase protein, wherein the mutation inactivates the glucokinase protein or has a negative effect on expression of the gene, and wherein the strain carries a mutation in the promoter region of the GalK gene encoding a galactokinase protein.

摘要： The invention relates to a composition for producing a fermented milk product comprising: (i) a starter culture comprising a glucose-fermenting Streptococcus thermophilus (St) strain and a glucose-fermenting Lactobacillus delbrueckii subsp. bulgaricus (Lb) strain; and (ii) a glucose-deficient Streptococcus thermophilus (St) strain, wherein said St strain is galactose-fermenting and carries a mutation in the DNA sequence of the glcK gene encoding a glucokinase protein, which mutation inactivates the glucokinase protein or has a negative effect on expression of the gene.
