Assessment of cell growth and ʟ-ornithine productivity of strains Orn8, Orn17(Orn8 carrying empty plasmid pEC-XK99E), Orn18(Orn8 carrying expression plasmid pEC-CgS09558), Orn19 (Orn8 carrying expression plasmid pEC-CgS14252), Orn20 (Orn8 carrying Ptac promoter inserted in the upstream region of CgS9114_09558), Orn21(Orn8 carrying Ptac promoter inserted in the upstream region of CgS9114_14252). a ʟ-ornithine production curves for strains Orn17, Orn18, and Orn19. b Cell growth curves for strains Orn17, Orn18, and Orn19. c ʟ-ornithine production curves for strains Orn8, Orn20, and Orn21. b Cell growth curves for strains Orn8, Orn20, and Orn21. Samples were collected per 12 h for fermentation parameter determination. Data represent average values and standard deviations from three individual experiments
