For systems not tested, the DoD Components are assessing on a case-by-case basis to determine if the systems may be impacted and needs testing. Degradation of perfluorooctanesulfonate in a laccase-mediator system. Q. Huang.
Biodegradation is simply the metabolism of anthropogenic, or otherwise unwanted, chemicals in our environment, typically by microorganisms. The metabolism of compounds commonly found in living things is limited to several thousand metabolites whereas ∼100 million chemical substances have been devised by chemical synthesis, and ∼100 000 are used commercially.

Perfluorooctanesulfonate Degrades in a Laccase-Mediator System Author: Luo, Qi, Yan, Xiufen, Lu, Junhe, Huang, Qingguo Source: Environmental science & technology 2018 A number of studies have confirmed the potential of laccase-mediator systems for paper pulp delignification [18,19], pitch control , polymer modification , other applications in the forest industry , and bioethanol production from physically and/or chemically pretreated lignocellulose . Pretreatment with laccase and a phenolic mediator degrades lignin and enhances saccharification of Eucalyptus feedstock. Biotechnology for Biofuels, 2014. Jorge Rencoret. Perfluorooctanesulfonate Degrades in a Laccase-Mediator System Qi Luo, Xiufen Yan, Junhe Lu and Qingguo Huang Effect of perfluorooctanesulfonate (PFOS) Perfluorooctanesulfonic acid (PFOS) (conjugate base perfluorooctanesulfonate) is an anthropogenic fluorosurfactant and global pollutant.
