Figure 1From: Acid stress response and protein induction in Campylobacter jejuni isolates with different acid toleranceGrowth of the different Campylobacter jejuni strains in chemically defined broth (CDB) containing different concentrations of methionine. Strains 11168 (A), 327 (B), and 305 (C) grown at 37°C in a microaerobic atmosphere in brain heart infusion (BHI) broth (dashed curve) and modified CDB containing 0.1 mM (■), 0.01 mM (▲), 0.001 mM (♦), and no (●) methionine, respectively. Error bars represent the standard deviation for three replicates.Back to article page
