Bacteria Could Help Clean “Forever Chemicals,” Scientists Find New Hope for PFAS Cleanup
Researchers at the University of Nebraska Lincoln have found a surprising ally in the fight against toxic “forever chemicals.” Their study revealed that a common photosynthetic bacterium might help capture and contain PFAS, one of the planet’s toughest pollutants.
A Promising Microbial Discovery
In experiments led by Dr. Rajib Saha and Dr. Nirupam Aich, scientists discovered that the bacterium Rhodopseudomonas palustris interacts with perfluorooctanoic acid (PFOA). This chemical belongs to the notorious PFAS family, known for resisting breakdown in water and soil.The bacterium absorbed PFOA into its cell membrane, and this interaction changed over time. As a result, researchers believe the microbe could serve as a foundation for future bioremediation methods.
Lab Findings and Current Challenges
During experiments, R. palustris removed about 44% of PFOA within 20 days. However, some of the chemical was released later, likely when bacterial cells broke down. This showed both potential and limitations — the bacterium can trap PFAS but cannot yet destroy it.
Dr. Saha explained that this discovery opens doors to genetic and systems biology research that might enhance the bacterium’s ability to retain or even transform PFAS.
Collaboration and Future Directions
Dr. Aich’s lab provided chemical analysis expertise, helping track PFOA behavior. Together, both teams demonstrated how combining microbiology, chemical engineering, and environmental science can lead to cleaner water solutions.PFAS pollution remains a global concern. However, this bacterial breakthrough marks a hopeful step toward safer, more sustainable cleanup technologies.
