Appeal No. 1997-4381
Application 08/440,734
Claims 1 and 9 are illustrative of the claims on appeal and read as follows:
1. A method of controlling bacteriophage attack on cheese making bacteria used
in a cheese making process, comprising:
treating a blocker peptide precursor selected from a group consisting of a source of
immunoglobulins, bacteriophages to which cheese making bacteria are sensitive,
bacteriophage parts to which cheese making bacteria are sensitive and mixtures thereof
with a protease enzyme that hydrolyzes the blocker peptide precursor;
collecting blocker peptides produced by hydrolysis of the blocker peptide
precursor;
formulating a starter mediate with the blocker peptides and heat treating the
formulated started media;
growing bulk cultures of cheese making bacteria used in the cheese making
process in the formulated starter media; and
adding cheese making bacteria grown in the formulated starter media to a
fermentation medium for producing cheese.
9. A method of making cheese with bacteriophage resistant cheese making
bacteria, comprising:
formulating a starter media with peptides that block bacteriophage attachment sites
on the cheese making bacteria;
growing bulk cultures of the cheese making bacteria in the formulated starter
media;
adding the cheese making bacteria grown in the formulated starter media to a
fermentation media for producing cheese whereby a curd is formed; and
cutting the curd.
