Figure 6.

CdtG shows possible sugar/proton symporter characteristics and Ls120451 does not. Exponentially growing cells expressing CdtG (A), Ls120451 (B), and the negative control YSS1 (C) were adjusted to pH 5, followed by addition of cellobiose to a 20 g/L final concentration (marked with light grey bar). The experiment was repeated with a pre-incubation with 25 µM CCCP for CdtG (D), Ls120451 (E), and the parental strain YSS1 as negative control (F). The data shown is the average from three replicates with the standard deviation shaded in grey.
