Purple indicator from E. coli

Georgia Tech graduate research assistant Daniel Watstein holds a plate containing E. coli that is producing a purple pigment in response to levels of zinc. The bacterium could be used to detect nutritional deficiencies in resource-limited areas of the world. Purple would indicate low levels of the micronutrient. (Credit: Rob Felt, Georgia Tech)
