Laccase-Catalyzed Degradation of Perfluorooctanoic Acid
Abstract
This study examined the decomposition of perfluorooctanoic acid (PFOA) in enzyme-catalyzed oxidative humification reactions (ECOHRs). ECOHRs make up a class of reactions that are ubiquitous in the environment. Approximately 50% of PFOA in a mineral buffer solution decomposed upon addition of laccase and 1-hydroxybenzotriazole after 157 days with a pseudo-first-order rate constant of 0.0044 day –1 ( r 2 = 0.89). No shorter carbon-chain perfluorocarboxylic acids were detected as degradation products during the experiment. However, partially fluorinated shorter-chain alcohols and aldehydes were identified by high-resolution mass spectrometry. These partially fluorinated compounds were likely products resulting from PFOA degradation via a combination of free radical decarboxylation, rearrangement, and coupling processes. Fluoride was detected in the reaction solution, and the concentration indicated a 28.2% defluorination ratio during the treatment. This finding suggests that PFOA may be transformed during humification, and ECOHRs can potentially be used for the remediation of PFOA.

In the citing paper
“As is the case for peroxidase-mediated defluorination, in laccase-mediated PFOA and PFOS degradation, the generation of partially fluorinated short-chain compounds was attributed to degradation via a combination of free-radical decarboxylation, coupling, and rearrangement processes (147, 149, 150), although more evidence is needed to understand this mechanism.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
