Multifunctional fabrics based on yeast dyes
Yarrowia lipolytica – YaLiGreen
One of the most promising alternatives to fossil-based dyes is their microbial production. Despite the many advantages over plant and animal dyes (e.g. non-competition with food, targeted molecule engineering, etc.), microbial dyes still face lower stability and higher production costs than synthetic dyes, which limits their industrial exploitation. Against this background, the YaLiGreen project aims to produce a green dye (prodeoxyviolacein) using a modified strain of Yarrowia lipolytica, extract the dye, and use it for textile dyeing.
The strategies to be followed in this project consist in 1) boosting the prodesoxyviolacein biosynthesis pathway in the yeast Y. lipolytica, 2) developing a culture medium based on industrial by-products for fermentation, 3) extracting and purifying prodesoxyviolacein, 4) functionalizing it to obtain color-stable fabrics, and 5) analyzing the antimicrobial activity and cytotoxicity of the dye and fabrics obtained.
