Living material offers new way to clean polluted water

Researchers at the University of California San Diego have developed a new type of material that could offer a sustainable and ecofriendly solution to clean pollutants from water. Dubbed an engineered living material, it is a 3Dprinted structure made of a seaweedbased polymer combined with bacteria that have been genetically engineered to produce an enzyme that transforms various organic pollutants into benign molecules. The bacteria were also engineered to selfdestruct in the presence of a molecular trigger. This offers a way to eliminate them after they have done their job.
