Metabolically evolved strain regained improved anaerobic cell growth. G) 20 g L−1 glucose NBS medium; X) 20 g L−1 xylose NBS medium; M) 20 g L−1 mixed glucose and xylose NBS medium. Symbols: open circle, JH14, initially engineered strain devoid of the glucose effect; filled circle, JH15, metabolically evolved strain from JH14. Each data point represents the average of three replicates. The error bar represents the standard deviations
