Abstract: Recommendations W e thank the authors for their interest in our work and for their comments.We were fully aware that our findings, that PFOA and PFOS can be defluorinated by the novel Acidimicrobium sp.strain A6, did challenge the belief that perfluorinated compounds may not be degradable.Hence, we did spend an extra year prior to publishing our results repeating the experiments and analyses multiple times, varying the electron donor for Acidimicrobium sp.strain A6 (NH 4 + and H 2 ), varying the initial PFOA/PFOS concentration, having PFAS analyzed by two separate commercial laboratories, and analyzing fluoride via two different IC methods as well as using a fluoride-specific probe.Incubations were done with multiple controls, including autoclaved, a control without NH 4 + , and
