Summary

LACTIC ACID STARTER CULTURES WERE FREEZE-DRIED IN WHEY AND NON-FAT SKIM MILK (NFSM) SUSPENDING MEDIA WITH VARYING AMOUNTS OF GLYCEROL, ADONITOL AND SUCROSE ADDITIVES. BEST RESULTS WERE OBTAINED WITHFREEZE-DRIED LACTOBACILLUS BULGARICUS WITH 0.29 M SUCROSE, 0.75 M ADONITOL OR 0.75 M GLYCEROL IN WHEY MEDIUM. THE BEST PROTECTION WITH STREPTOCOCCUS THERMOPHILUS WAS OBTAINED WITH 1, 0.5 AND 0.75 M ADONITOL IN NFSM MEDIUM AND 1 M ADONITOL IN WHEY MEDIUM. ACTIVITY LOSS AND VIABILITY LOSS WERE PARALLEL DURING STORAGE ; OCCASIONAL DEVIATION FROM A PARALLEL TREND OCCURRED DUE TO THE PRESENCE OF INJURED MICRO-ORGANISMS. (DAIRY SCI.
