Inoculum in stationary phase of growth (A) and in logarithmic phase of growth (B) for Pa1 (NaCl MBC: 7%). Bacterial suspension in NaCl at the MBC value were incubated at 37°C (green dotted line, open circles) or 4°C (red dotted line, filled circles). Controls (full lines) were not exposed to NaCl and were incubated at 37°C (green line, open circles) or 4°C (red line, filled circles). The horizontal dotted line indicates a 4-log reduction in viability. B: dotted green (open circles) and red (filled circles) lines are superposed.
