Application of the growth-regulated promoter to replace the native promoters of the aceE and gltA genes. a Cell densities of different strains. b Relative transcriptional levels of the aceE and gltA genes under the control of the growth-regulated promoter in reference to their native promoters. c Relative activity of pyruvate dehydrogenase and citrate synthase between stationary phase and exponential phase. Exp exponential phase, Sta stationary phase. Means ± standard deviations were calculated from three biological replicates
