by Luo, Qi, Evaluating perfluorooctanesulfonate oxidation in permanganate systems. By Saerom Park, Linda S Lee, Ian Ross, and Jake Hurst Environ. Sci. and Poll. Res. February 18, 2020 DOI: 10.1007/s11356-020-07803-7. Permanganate (PM) has shown to be able to oxidize a range of organic contaminants including perfluorooctane sulfonate (PFOS). Use of pesticides is usually related to overproduction of crops in order to overcome worldwide demand of food and alimentary safety.

Perfluorooctanesulfonate degrades in a laccase-mediator system

The treatments with laccase alone (without mediator) decreased the lignin content about 12% and 20% when using laccase doses of 10 U · g -1 and 50 U · g -1, respectively. Table 1. Lignin content and monosaccharides release (% of sample weight) by cellulase hydrolysis of eucalypt samples. Eucalypt samples. Sigma-Aldrich offers abstracts and full-text articles by [Qi Luo, Xiufen Yan, Junhe Lu, Qingguo Huang].

Plant cell-wall deconstruction, however, remains an inefficient process, mainly due to the recalcitrant nature of the lignin and cellulosic components, that requires chemical pretreatment methods prior to degradation.

2: Non-DoD purveyor tested most of these systems so far as required under the EPA's Unregulated Contaminant Monitoring Rule 3 or per request from DoD. 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.
