Amino acid production by various C. glutamicum strains. L-ornithine production by C. glutamicum CIT0(pVWEx1) (filled squares) (A) and L-citrulline accumulation (filled squares) and glucose consumption (open triangles) by strain CIT0(pVWEx1-argFBfbr) (B). The experiments were performed in CGXII minimal medium with 20 g/L glucose, 1 mM IPTG, 25 μg/L kanamycin and supplemented with 750 μM L-arginine. Values and error bars represent the mean and the standard error of triplicates.
