n-Butanol production with n-butanol pathway (pVS6) and coaA overexpression under control of the MET25 promoter (pVS5_4) in CEN.PK113-5D with addition of methionine. Five different concentrations of methionine were added to SMD medium: 0Â mM (diamond), 0.125Â mM (cross), 0.25Â mM (circle), 0.5Â mM (triangle), and 2Â mM (square). Error bars represent the standard deviation of three independent replicates
