Measurement of cell growth, ʟ-ornithine productivity, and glucose consumption performed by strain Orn8, Orn22 (Orn8 with deletion of CgS9114_13845), Orn23 (Orn8 with deletion of CgS9114_02593), Orn24 (Orn8 with deletion of CgS9114_02058), Orn25 (Orn8 with deletion of CgS9114_14352), Orn26 (Orn8 with deletion of CgS9114_04952), Orn27 (Orn8 with deletion of CgS9114_14497). a ʟ-ornithine production curves for strains Orn8 (black square), Orn22 (red circle), Orn23 (blue upper triangle), Orn24(pink lower triangle). b Cell growth of strain Orn8, Orn22, Orn23, and Orn24. c Residual glucose concentration curves of strain Orn8, Orn22, Orn23, and Orn24. d ʟ-ornithine production curves for strains Orn8 (black square), Orn25 (dull-red pentagon), Orn26 (green pentacle), Orn27(purple left triangle). Samples were collected per 12 h for fermentation parameter determination. Data represent the average values and standard deviations from three individual experiments
