Effect of valinomycin on L. plantarum growth and intracellular leucine content under different acidic conditions. The effect of valinomycin on the growth of L. plantarum was measured spectrophotometrically at 600 nm and visibly monitored (a). L. plantarum was cultivated with 0, 5, 10, 20, 40, 80, or 160 μg/ml valinomycin. The L. plantarum growth and intracellular leucine content was determined at pH 6.2 (b,e), pH 5.5 (c,f), and pH 5.0 (d,g), respectively. The red line and grey bar indicate the presence of 10 µg/ml valinomycin (*p < 0.05).
