E.chromi Bacteria Color Codes Poop as a Disease Alert System

E.chromi is a project created by designers and synthetic biology scientists at Cambridge University in 2009. They genetically engineered bacteria to “secrete a variety of coloured pigments, visible to the naked eye”. BioBricks, standarized sequences of DNA, are inserted into E. coli bacteria, which creates a color coding system to monitor for disease. A special beverage loaded with this engineered E.coli bacteria is consumed by sick patients who can then diagnose their disease simply by looking at the color of their poop.
