Decrease of transmembrane ΔpH of L. plantarum upon incubation with reutericyclin (○) or nisin (•). The buffer pH was 5.0, and the internal pH of L. plantarum in the absence of inhibitors was 6.6 ± 0.3. The results indicate the means ± standard deviations of three independent experiments. Corresponding results were obtained with L. sanfranciscensis (data not shown).
