pH vs. MICMs of the 96 C. jejuni strains against the six dissociated organic acids—propionic, l-lactic, formic, citric, butyric, and acetic acid. The number of strains is displayed adjacent to each MICM data point. The small, light green, vertical box at 20.39 mM shows the inhibition of 100% of the strains by dissociated citric acid. The larger light blue vertical box (22.72 to 24.86 mM) encloses the inhibition of 97–99% of the C. jejuni strains by dissociated butyric, propionic, and acetic acid, Δ = 2.14 mM. The magenta vertical box (35.11 to 36.36 mM) encloses the inhibition of 97–99% of the C. jejuni strains by dissociated l-lactic and propionic acid, Δ = 1.25 mM. Each pH data point is the mean and standard deviation of triplicate samples.
