Abstract

L'invention concerne les séquences d'ADN complètes des gènes adhE et pfl de Lactococcus lactis, des réplicons recombinants contenant un de ces gènes ou les deux, ou leurs mutants ou variants, notamment des mutants dans lesquels les gènes sont inactivés, ainsi que des bactéries lactiques recombinantes contenant un réplicon de ce type. Les séquences géniques et/ou les séquences régulant l'expression des gènes peuvent être modifiées de façon à donner des bactéries lactiques à métabolisme modifié, qui produisent de manière augmentée ou diminuée un ou plusieurs métabolites résultant de la fermentation du citrate et/ou du sucre. Les cellules ainsi modifiées sont utiles comme cultures starters pour la fabrication de produits alimentaires et d'aliments pour animaux ayant un goût amélioré et/ou une durée de conservation accrue, notamment les produits laitiers, ou peuvent être utilisées directement pour la fabrication d'un métabolite des bactéries lactiques.
