Comparison of final optical density (black) and l-phenylalanine production (gray) in 48 h flask cultivation. a All five engineered E. coli strains (YHP01 to YHP05) and the parental E. coli W3110 were cultivated and cell growth (OD600) and l-phenylalanine production titers were compared. b E. coli YHP05 strain harboring different plasmids (pTac15kG series or pYHP) were cultivated and cell growth (OD600) and l-phenylalanine production titers were compared. Error bars represent standard deviation of the mean (n = 3)
