Figure 2.

Comparison of the different C. glutamicum strains during cultivation in shake-flasks with the fermentation medium, to test the effect of inserting leuAilvBNCE. (A) ΔLtbR /pECXK99E (pECXK99E was used here as a control plasmid), (B) ΔLtbR/ABNCE, (C) by-products, and (D) NADPH/NADP⁺ ratio. Solid squares—OD₅₆₂, hollow triangles—glucose, solid triangles—l-leucine: hollow circles—l-valine. The data represent the mean values and standard deviations obtained from three independent cultivations.
