Abstract: 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.
