Abstract
The invention relates to the use of mutants of L. casei having at least a mutation impairing the regulation of a carbon catabolite repression (CCR) mechanism involving the PTS protein HPr, for the preparation of a food product. The use of said mutants allows for instance to impart to said food products an improved texture and flavor, and/or a higher content in aroma compounds.
Claims5
A method for preparing a food product or food additive, wherein said method comprises fermenting a food substrate with a mutant of L. casei having at least one mutation in the ptsI gene, wherein said mutation impairs the regulation of carbon catabolite repression mechanisms.
A fermented food product comprising at least a mutant of L. casei having at least one mutation in the ptsI gene, wherein said mutation impairs the regulation of carbon catabolite repression mechanisms.
