University of California, Riverside, chemical and environmental engineering scientists have identified two species of bacteria found in soil that break down a class of stubborn “forever chemicals,” giving hope for low-cost biological cleanup of industrial pollutants.
These bacteria destroy a subgroup of per- and poly-fluoroalkyl substances, or PFAS, that have one or more chlorine atoms within their chemical structure, Yujie Men, an assistant professor in the Bourns College of Engineering, and her UCR colleagues, reported in the journal Natural Water.
Unhealthful forever chemicals persist in the environment for decades or much longer because of their unusually strong carbon-to-fluorine bonds. Remarkably, the UCR team found that the bacteria cleave the pollutant’s chlorine-carbon bonds, which starts a chain of reactions that destroy the forever chemical structures, rendering them harmless.
