   Can Indican be made without toxic chemicals?

   • Researchers in Denmark have engineered an improved dyeing method that eliminates the need for harsh chemicals, instead using an enzyme for dyeing. This technology, outlined in a study published today in Nature Communications, could enable large-scale production and application of indican, a molecule related to indigo, without toxic chemicals.

   Can Indican be used in denim dyeing?

   • To efficiently leverage indican in denim dyeing, two processes must be developed that have environmental benefits over the conventional method while still being affordable: a production process (Fig. 1A ), and a dyeing process (Fig. 1B ). Fig. 1: Overview of indigo and indican production and use.

   How is indican biosynthesised?

   • Clark et al. (1993). Surprisingly, indican is also biosynthesised in the human body from the amino acid tryptophan. Part of the indican is degraded by intestinal bacteria to the smelly indole. Some of the colourless and water soluble indican is also eliminated via the kidneys.

   Is indican a reducing agent?

   • The glucoside, indican, is stable in air and can be stored. The glucosyl group is removed only at the point of dyeing, allowing the regenerated indoxyl to oxidize to indigo crystals in cotton fibers. No reducing agent is required when dyeing with indican. BGL, β-glucosidase; UGT, UDP-glycosyltransferase.

   Steeping the woad leaves in warm water breaks down the waxy coating on the leaves releasing the precursors indican and isatan into the water. By adding soda ash you raise the pH making the solution alkaline which transforms the indican into molecules of indoxyl.

   The indican is split into indoxyl and glucose by an enzyme, indigoemulsin (indoxylase), contained in the indigo leaves. At the same time microorganisms generate hydrogen as a reducing agent and the dye becomes water soluble.
