Fig. 3From: Modular systems metabolic engineering enables balancing of relevant pathways for l-histidine production with Corynebacterium glutamicumSystems metabolic profiling (SMP) of l-histidine-producer strains C. glutamicum HIS1, HIS6–HIS10 and C. glutamicum ATCC 13032 (WT). Intracellular peak intensities of each metabolite are given as bar plots. Corresponding strains can be identified per legend in the top right corner. Error bars give standard deviation of three independently performed experiments. Abbreviations can be found in Fig. 1Back to article page
