Effect of preexposure to organic acid on tolerance of S. Typhimurium to desiccation. Bacterial cells were exposed to 50 mM citric acid at pH 3.0 for 1 h prior to desiccation. Cells incubated in SDW were used as a control. The average numbers (+ standard deviations) of surviving cells from three independent experiments are presented. Means followed by different letters indicate a significant difference between desiccated and nondesiccated cells (P < 0.01).
