THE EFFECT OF THE PSYCHROTROPHIC STRAIN (VIA ITS ENZYMES) ON THE QUALITY OF FETA CHEESE PRODUCED BASED ON CONSTITUENT ANALYSIS ANDCOMPARISON WITH CONTROL CHEESE WAS STUDIED.

THE PRODUCTION AND ACTIVITY OF THE ENZYMES WERE SIGNIFICANT UNDER \"INDUSTRIAL\" CONDITIONS, 3. THE PROTEASE WAS CHARACTERIZED TO BE AS THIOL ENZYME AND CONTAIN CU AND CA IN ITS MOLECULE, 4.
