From: Metabolic engineering of Escherichia coli to optimize melanin synthesis from glucose
Profiles from bioreactor cultures for the production of melanin and L-tyrosine using mineral media supplemented with glucose as carbon source. (A) Biomass concentration, (B) glucose concentration, (C) L-tyrosine (filled symbols) and melanin (empty symbols) concentration. (▲) strain VH33GTR, (■) strain VH33MGTR. Graphs represent the mean of duplicate experiments. Percentage errors for data from strain VH33GTR were 4.48, 14.02 and 9.16% for biomass, glucose and L-tyrosine concentrations, respectively. Percentage errors for data from strain VH33MGTR were 15.64, 10.49, 8.03 and 16.07% for biomass, glucose, L-tyrosine and melanin concentrations, respectively.
