Bacterial litmus test for micronutrients

A bacterium engineered to produce different pigments in response to varying levels of a micronutrient in blood samples could give health officials an inexpensive way to detect nutritional deficiencies in resource-limited areas of the world. This “bacterial litmus test,” which currently measures levels of zinc, would require no electrical equipment and make results visible as simple color changes.
