ʟ-Ornithine productivity, cell growth, and glucose consumption during cultivation of SO1, SO10 (SO1 carrying P _eftu promoter inserted upstream of pfkA and P _tac promoter inserted upstream of cg3035), SO11 (SO1 carrying P _eftu promoter inserted upstream of pfkA, P _tac promoter inserted upstream of cg3035 and terminator inserted in the upstream region of cat), SO12 (SO1 carrying the P _eftu promoter inserted upstream of pfkA, P _tac promoter inserted upstream of cg3035, and a terminator inserted upstream region of pta), and SO13 (SO1 carrying the P _eftu promoter inserted upstream of pfkA, P _tac promoter inserted upstream of cg3035, and a terminator inserted in the upstream region of pta and cat). a ʟ-Ornithine production curves for strains SO1 (black square), SO10 (red circle), SO11 (blue upper triangle), SO12 (pink lower triangle), and SO13 (green quadrangle). b Cell growth and glucose consumption. Samples were collected per 12 h for fermentation parameter determination. Data represent the average values and standard deviations from three individual experiments
