Variability in growth limits of Listeria monocytogenes in response to low pH (adjusted with HCl) or high salinity (NaCl) was evaluated for 127 strains in brain heart infusion broth at 25 degrees C. Over 95% of strains habituated at pH 5.0 grew subsequently at pH 4.2, while 25% were able to grow at pH 4.1. More than 85% of strains preadapted to growth at 8.5% NaCl (wt/vol) subsequently grew in the presence of 11.3% NaCl, while 25% were able to grow at 13% NaCl, and 4.7% grew in the presence of… CONTINUE READING
