Desulfonation and defluorination of 6:2 fluorotelomer sulfonic acid (6:2 FTSA) by Rhodococcus jostii RHA1: Carbon and sulfur sources, enzymes, and pathways

The compound 6:2 FTSA (6:2 Fluorotelomer Sulfonic Acid) is an important PFAS as it is used in a majority of contemporary products including AFFF formulations and chromium plating anti-mist solutions. This study shows that used microorganisims are able to completely degrade the 6:2 FTSA rapidly leading to a series of PFAS terminal metabolites. All parties…
