Pili, is using microbial fermentation to produce sustainable textile dyes. They are developing a completely new dye technology, designing enzymatic cascades that turn renewable carbon feedstocks, such as sugar, into textile dyes. Using the specificity and efficiency of enzymes, they can produce dyes for a wide variety of color hues and applications.

Highlights and sustainability benefits

The bacteria are grown in water-based bioreactors, using sugar as their main food source. This process requires no fossil fuels and no toxic inputs, and produces no harmful byproducts, making our bacterial biofactories both highly efficient and non-polluting.


The technology can be scaled up for high production, lowering costs without sacrificing quality.

About the Work

Pili bio-synthesizes dyes from sugar using fermentation processes without any solvents or the need to heat at high temperatures. Their technology is based on microbial enzymes, re-engineered to produce brilliant and effective dyes from renewable resources. Once biosynthesized the pigments are filtered out leaving the microorganisms for further uses. The dyes are finally purify them so that they can be used in a wide range of industrial applications, especially in the textile industry.

About the Innovator

Using fermentation technology, Pili is bio-synthesizing dyes using microbes, specifically designed for the textile industry. They are working in two French-based laboratories: one where they bioengineer the microbes and and the other where they develop green extraction methodologies and test the properties of our bio-dyes.
