Fig. 2From: Molecular adaptation of Lactobacillus plantarum WCFS1 to gallic acid revealed by genome-scale transcriptomic signature and physiological analysisEnergetics of gallic acid metabolism in L. plantarum WCFS1. The internal pH (a, c) and the membrane potential (b, d) of GA-induced cells (c, d) and non-induced cells (a, b) were continuously tracked in time. GA (1.5 mM) was added at the times indicated by the arrows. Cells were loaded with BCECF as described in “Methods”. Variations in membrane potential were quantitatively evaluated from the quenching of the potentiometric probe DisC3 Back to article page
