Abstract: 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.
