Summary

AUTOCLAVED SAMPLES OF SKIM MILK WERE INOCULATED WITH LISTERIA MONOCYTOGENES (STRAIN SCOTT A, CALIFORNIA OR V7), PSEUDOMONAS FLUORESCENS (STRAIN P26 OR B52), OR A COMBINATION OF L. MONOCYTOGENES PLUS P. FLUORESCENS, AND INCUBATED AT 280 OR 286 K FOR 8 WEEKS. GROWTHOF L. MONOCYTOGENES WAS SOMEWHAT ENHANCED 7 DAYS AT 280 K BUT NOT AT 286 K IN THE PRESENCE OF PSEUDOMONADS. AFTER 14 DAYS UNTIL THE END OF THE INCUBATION PERIOD (56 DAYS), SLIGHT INACTIVATION OF L. MONOCYTOGENES IN THE PRESENCE OF P. FLUORESCENS WAS OBSERVED. NO MARKED CHANGES IN PH OF THE MILK WERE CAUSED EITHER BY L. MONOCYTOGENES ALONE OR BY L. MONOCYTOGENES PLUS P. FLUORESCENS.
