Bacteria Display Potential in Tackling PFAS Chemicals
A team of researchers led by SUNY Distinguished Professor Diana Aga has discovered a bacterial strain that can effectively break down perfluoroalkyl substances (PFAS), which are highly persistent and toxic chemicals. The study, published in *Science of the Total Environment*, highlights the potential of *Labrys portucalensis F11* bacteria to transform PFAS into less harmful metabolites.
The bacteria successfully degraded over 90% of PFOS (a type of PFAS) within 194 days and even removed fluorine from three PFOS-derived metabolites. This breakthrough could revolutionize the remediation of PFAS-contaminated environments, such as wastewater or soil. The strain can also process other PFAS chemicals like 5:3 FTCA and 6:2 FTS.
The study suggests that *Labrys portucalensis F11* may be used to enhance environmental cleanup efforts by improving the efficiency of natural remediation processes. However, further research is needed to optimize its use in industrial applications. This discovery marks a significant step forward in addressing PFAS pollution and protecting our ecosystems from these harmful chemicals.
