Flask cultivation for l-threonine production in E. coli strains TWF066, TWF069, TWF070, TWF071, TWF072, TWF073, TWF074, TWF075, TWF076, TWF077, TWF078, TWF079, TWF080, TWF081, TWF082 and TWF083. a Genetic comparison of the strains constructed by dynamic regulation genes arcA, cpxR, gadE, pykF and fadR. b Cell growth; cl-threonine production. The error bars indicate the standard deviations from three independent experiments
