Their process relies on the capability of microorganisms to biosynthesise naturally complex molecules with their secondary metabolism. The main goals and challenges for the upcoming months will be to bring down the cost of production of PILI dyes to the level of plant ones and to start the scaling of bioproductions. For the former they will use agile synthetic biology approaches to iterate on the optimisation of the synthesis pathways of our dyes. The initial goal was to produce bio-inks for pens and printers. Now they are collaborating with BIC, one of the world leaders for pen design and distribution. Pili is still at an early stage but with the right supports and collaborations they expect to release of the first products by 2016.
