Zusammenfassung:	The invention concerns lactic acid bacteria strains wherein the phosphorylable histidine of the IIA domain of lactose permease is replaced by a non-phosphorylable amino acid. Said strains have a reduced post-acidification and are useful in particular for preparing fermented dairy products. L'invention est relative à des souches de bactéries lactiques chez lesquelles l'histidine phosphorylable du domaine IIA de la lactose perméase est remplacée par un acide aminé non phosphorylable. Ces souches possèdent une post-acidification réduite et sont utilisables notamment pour la préparation de produits laitiers fermentés.
