Sugar signaling response of XI, XR/XDH and control strains. Normalized mean fluorescence intensity of the SUC2p-yEGFP biosensor over time during anaerobic cultivation in YNB medium supplemented with 50 g L−1 xylose. Biological duplicates were performed. ClosXI: XI from Lachnoclostridium phytofermentans, epi: xylose epimerase
