MUTANT STRAINS OF LACTIC ACID BACTERIA HAVING A NON-PHOSPORYLABLE LACTOSE PERMEASE

摘要

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.
