Summary

THE EFFECTS AND INTERACTIONS OF TEMPERATURE: 278, 292, 301 AND 310 K (5, 19, 28 AND 37 DEG C), INITIAL PH (6.0 AND 7.5), ATMOSPHERE (AEROBIC AND ANAEROBIC), SODIUM CHLORIDE CONTENT (0.5 AND 4.5%), AND SODIUM NITRITE CONCENTRATION (0, 50, 100, 200, 1,000 MICROGRAMME/MILLILITRE) ON THE GROWTH OF LISTERIA MONOCYTOGENES SCOTT A WERE DETERMINED. THE DATA INDICATED THAT THE GROWTH KINETICS OF L. MONOCYTOGENES WAS DEPENDENT ON THE INTERACTION OF THE 5 VARIABLES, PARTICULARLY IN REGARD TO EXPONENTIAL GROWTH RATES AND LAG PHASE DURATIONS. SODIUM NITRITE CAN HAVE SIGNIFICANT BACTERIOSTATIC ACTIVITY AND MAY PROVIDE CURED MEATS WITH A DEGREE OF PROTECTION AGAINST THIS MICRO-ORGANISM, PARTICULARLY IF EMPLOYED IN CONJUNCTION WITH A COMBINATION OF ACIDIC PH, VACUUM PACKAGING, HIGH SALT CONCENTRATIONS, AND ADEQUATE REFRIGERATION.
