Pili bio-colour and pigments with microbes
Pili are developing a cell factory that uses an enzyme based process to convert sugars into colour, using a technique similar to fermenting beer. The genes for each enzyme are integrated into bacteria or other microorganism. These 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 the bacterial biofactories both highly efficient and non-polluting. At the end of the process the pigment is separated by filtration. Image Pili.
