Comparative fermentation assays of EBY_Xyl1 expressing different transporters in xylose (full lines) or glucose (dashed lines). a Growth of EBY_Xyl1 during xylose fermentation. b Xylose consumption of EBY_Xyl1 cells expressing the transporters over time. Note that SpX does not appear clearly as it overlaps with SpG. c Growth of EBY_Xyl1 expressing SuL, GXF1 as positive control and pRS426 (empty vector) as negative control during xylose/glucose co-fermentation and d sugar consumption of EBY_Xyl1 expressing SuL, GXF1 as positive control and pRS426 (empty vector) as negative control during xylose/glucose co-fermentation (note that SuL glucose fermentation overlaps with GXF1)
