Figure 3From: L-citrulline production by metabolically engineered Corynebacterium glutamicum from glucose and alternative carbon sourcesBiomass formation and production of ornithine and citrulline on glucose by various C. glutamicum strains: cell dry weight (hatched bars), L-ornithine concentration (open bars) and L-citrulline concentration (filled bars). The cultivation was performed in CGXII minimal medium containing 20 g/L glucose, 1 mM IPTG, 750 μM L-arginine and 25 μg/L kanamycin. The amino acid concentrations in the supernatant were determined after the consumption of glucose. Values and error bars represent the mean and the standard error of triplicates.Back to article page
