Abstract
A biosynthetic method and composition for producing an Indigo dyestuff including Indigotin and Indirubin. Tryptophanase (TRP) and flavin-containing monooxygenase (FMO) are generated from a genetically-modified organism having a vector coding for tryptophanase and flavin-containing monooxygenase. The conversion of L-tryptophan to Indigo dyestuff is converted by the generated TRP and FMO in the presence of one or more bioactive additives selected from the cysteine, 2-oxindole, or 2-indoxyl to form a dyestuff having a ratio of Indigotin to Indirubin by weight between 1:0.1 to 1:4. The dyestuff has a color hue defined by CIE XYZ color space with X: 0.1920 to 0.2481, Y: 0.2537 to 0.2019, Z: 0.5543 to 0.5501. Selectable and reproduceable color hues are provided.
