In this episode of Smart Water Solutions, co-hosted by Rhea and I, we had the privilege of speaking with Peter Jaffé, a distinguished Professor of Civil and Environmental Engineering at Princeton University. Professor Jaffé shared insights into his pioneering research on environmental bioremediation, specifically his work on a bacteria strain adept at breaking down per- and polyfluoroalkyl substances (PFAS), notorious for their persistence in the environment. The conversation discusses the bacteria's unique ability to thrive in acidic, iron-rich conditions and its specialized metabolic pathways that facilitate the degradation of these stubborn pollutants (e.g. PFAS). Professor Jaffé detailed the scientific journey of discovering and understanding this bioremediation process, highlighting the crucial electron transfer mechanisms involved. This episode offers an in-depth look at the innovative strategies being developed to combat pollution, promising a new path in water treatment and environmental restoration.
