Plasmid with the lycopene pathway was introduced into ST1, ST2, and ST8 (STL1, STL2, STL8, respectively). The strains were cultivated in flasks containing 2X M9 medium. a The growth profile, b acetate production, and c lycopene production of STL1, STL2, and STL8 are presented. Data of STL1, STL2, and STL8 are represented by black, red, and blue lines, respectively. d The specific yield of lycopene was calculated in the early stationary phase of cultivation. The samples of STL1, STL2, and STL8 were taken at 24 h, 36 h, and 48 h, respectively to calculate specific yield of lycopene. All data are averaged through three independent experiments
