Summary

STUDIES WERE CONDUCTED ON THE VIABILITY OF MICROCOCCUS VARIANS STRAIN M95 AND LACTOBACILLUS PLANTARUM STRAIN L4 UPON FREEZING AND FREEZE-DRYING USING FIVE CRYOPROTECTANTS (SUCROSE, LACTOSE, SODIUM GLUTAMATE, PEPTONE, DRY NONFAT MILK) SINGLY OR IN COMBINATIONS WITH GELATIN, GLUTAMIC ACID, AND SODIUM ACETATE. THE NUMBER OF SURVIVALS WAS DETERMINED IMMEDIATELY AFTER TREATMENT AND AFTER STORAGE AT ROOM TEMPERATURE OR REFRIGERATION TEMPERATURES, UNDER VACUUM OR IN AIR. THE BEST RESULTS ARE OBTAINED ON STORING THE MICROORGANISMS UNDER VACUUM IN AMPOULES UNDER REDUCED TEMPERATURES 5 DEG C.
