From: Efficient anaerobic consumption of D-xylose by E. coli BL21(DE3) via xylR adaptive mutation
Anaerobic cell growth and fermentation profiles of the BL21(DE3) E. coli strain and adaptively evolved strains in fermentation medium containing both D-glucose (12.5 mM) and D-xylose (12.5 mM), or fermentation medium containing D-xylose only (25 mM). A BL21(DE3) in D-glucose + D-xylose, B BL21(DE3) in D-xylose, C JH001 in D-glucose + D-xylose, D JH001 in D-xylose, E JH019 in D-glucose + D-xylose, and F JH019 in D-xylose
