Fig. 5From: Expanding metabolic pathway for de novo biosynthesis of the chiral pharmaceutical intermediate l-pipecolic acid in Escherichia coli Effect of Fe2+ and surfactant on l-pipecolic acid fermentation. The filled bar represents OD600, the bar with backslash represents l-pipecolic acid titer (g/L), the unfilled bar represents l-pipecolic acid specific productivity (g l-PA/g DCW). a The effect of Fe2+ on l-pipecolic acid fermentation. b The effect of surfactant on l-pipecolic acid fermentationBack to article page
