Fig.2. Comparison of the effects of xylAB genes from different strains.
a: Growth curve (solid) and xylose consumption (hollow) curves. b: L‑Ornithine production curves. Strain pX (hollow circular) is a control strain containing pXMJ19, Strain XAB (hollow square) overexpressesxylAB from E. coil , Strain EAB (hollow upper triangle) overexpresses xylAB from X. campestris .
