US Patent Number
A method is provided for reducing or preventing bacteriophage attack on bacteria used in a cheese making process. The method includes (a) treating a blocker peptide precursor with a protease enzyme that hydrolyzes the precursor to produce blocker peptides; (b) collecting the blocker peptides so produced; (c) formulating a starter media with the blocker peptides; (d) growing bulk cultures of cheese making bacteria in the inoculated starter media; and (e) adding bacteria grown in the inoculated starter media to a fermentation medium for producing cheese. The present invention also includes a method of making cheese and cheese produced by the method.
