Figure 3From: Metabolic engineering of Escherichia coli to optimize melanin synthesis from glucoseCulture profiles carried out in shaken flasks with strains modified for melanin production from glucose (ca. 10 g/L). CuSO 4 was added at the beginning of the stationary phase. Symbols for strains: *W3110M, ■ W3110MG, ▲ W3110MGT, ▼VH33MGT, ♦ VH33MGTR and ● VH33MGTRK. Graphs represent the mean of three independent experiments.Back to article page
