Co-consumption of cellobiose and xylose of engineered cellobiose-positive chassis of C. glutamicum strains. Two different cellobiose-negative strains (Cg-pBbEB1c and Cg-EcXylAB) and two different cellobiose-positive strains (Cg-Cello03-Xyl01 and Cg-Cello04-Xyl01) co-expressing XylA and XylB were tested. The cellobiose-negative strains were cultivated in CgXII medium with a mixture of 2 % (w/v) glucose and 1 % (w/v) xylose. On the other hand, the cellobiose-positive strains were cultivated in CgXII medium with a mixture of 2 % (w/v) cellobiose and 1 % (w/v) xylose. Growth (left panels; black circle), cellobiose (right panels; blue square), glucose (right panels; black triangle), xylose (right panels; red circle) were shown. Data represents mean values of at least three cultivations and error bars represent standard deviations
