Researchers have identified certain human gut bacterial strains capable of effectively sequestering perfluoroalkyl and polyfluoroalkyl substances (PFAS), commonly known as 'forever chemicals,' which accumulate in the environment and human tissues. Laboratory tests demonstrated that nine gut bacteria efficiently absorbed PFAS compounds within 24 hours, suggesting a potential natural mechanism to reduce PFAS bioaccumulation. The findings, published in Nature Microbiology, offer hope for novel bioremediation strategies leveraging the human microbiome.
