CAS :The maunfacturing of blue jeans started 150 years ago as workwear, and are found nowadays in almost every wardrobe. Their renowned indigo color tone is truly unique; nevertheless, the high demand for the dye poses serious sustainability and environmental problems connected with its manufacturing process. Recently, a group of scientists presented an alternative indigo dyeing method inspired by the indoxyl glucoconjugate present in the plant P.tinctorium. The researchers proposed as an alternative approach a biocatalytic process using recombinant E.coli to access water soluble β-gluco-indoxyl (indican). At the point of coloring, indican gets hydrolyzed by β-glucosidase enzymes forming indoxyl, which suddenly undergoes oxidation to leucoindigo and further crystallizes to indigo giving the typical blue denim its signature character.Formule :C14H17NO6Degré de pureté :Min. 99.0 Area-%Masse moléculaire :295.29 g/mol4-Nitrophenyl sulfate potassium salt
