Summary

THE INFLUENCE OF FLUCTUATING TEMPERATURES ON SOME IMPORTANT SPOILAGE BACTERIA, IE, BROCHOTHRIX THERMOSPHACTA, SERRATIA LIQUEFACIENS AND A LACTOBACILLUS SP, AS WELL AS VIBRIO SP AND YERSINIA ENTEROCOLITICA, WAS DETERMINED IN CULTURE AND IN VACUUM-PACKED BOLOGNA-TYPE SAUSAGE KEPT AT 271, 275 AND 278 K (-2, 2 AND 5 DEG C). THE RESULTS VARIED CONSIDERABLY AMONG THE ORGANISMS STUDIED. B. THERMOSPHACTA GREW IRRESPECTIVE OF TEMPERATURE, NUMBERS OF S. LIQUEFACIENS DECREASED EACH TIME THE PRODUCT WAS STORED AT 271 K BUT GREW AT TEMPERATURES ABOVE 273 K (0 DEG C). THE EFFECT ON THE LACTOBACILLUS SP DEPENDED ON THE INITIAL STORAGE TEMPERATURE, THERE WAS NO SIGNIFICANT DIFFERENCE IN NUMBERS OF Y. ENTEROCOLITICA. THE TIME-TEMPERATURE COMBINATION WAS THE DETERMINING FACTOR IN THE NUMBER OF BACTERIA PRESENT AFTER EQUIVALENT PERIODS AT THE TEMPERATURES ABOVE AND BELOW 273 K.
