The invention relates to a polynucleotide comprising a lacZ gene (lacZ) encoding a β-galactosidase characterized by a particular profile regarding its efficiency of hydrolysis of lactose. The invention is also directed to astrain comprising a lacZallele and bacterial composition thereof, and their use to obtain fermented milk not undergoing post-acidification.

Lactic acid bacteria

The invention relates to a lactose-positive, galactose-negative,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.
