Expression of xylAB and xylFGH improve xylose utilization in B. sacchari. Late-exponential cells grown in MMG were diluted 1:100 in MMX with arabinose (7.5 mM) and transferred to 96-well plates. Optical density (OD600) was measured in triplicate every 15 min for 24 h. The μmax increase (%) was determined by comparing the growth rate of each strain with the one expressing RFP (pF8k-RFP)
