Perfluorooctanesulfonate (PFOS) is a compound that has wide applications with extreme persistence in the environment and the potential to bioaccumulate, and could induce adverse effects to ecosystems. We investigated the degradation of PFOS by laccase-induced enzyme catalyzed oxidative humification reactions (ECOHRs) using 1-hydroxybenzotriazole

15). These laccase-mediator systems have been shown to de-grade not only lignin but also several aromatic and aliphatic xenobiotics (29, 39). The participation of laccase in the pro-duction of reduced oxygen species, i.e., superoxide anion rad-ical (O 2), H 2O 2, and OH, has been demonstrated through the oxidation of lignin-derived

Perfluorooctanesulfonate degrades in a laccase-mediator system

Pulp bleaching 2. The following PFOS and PFOA chemicals, with some exceptions, were used as pesticides or as EPA "Inerts" in pesticide products, until they were phased out of use since the story broke in 2000. Similarly, a reaction system composed of the fungal polyester hydrolase HiC and the lipase CalB from Candida antarctica also showed a 7.7‐fold increase in the yield of terephthalate obtained due to the concomitant degradation of MHET catalysed by CalB (Carniel et al., 2016). LMS laccase-mediator system Potential of C. rigida and its laccases in applied processes As mentioned before, C. rigida and its laccases are currently being studied in terms of their ability to degrade and/or detoxify a wide array of compounds such as industrial by-products and/or agricultural wastes. Plant biomass is an abundant renewable resource on Earth. Microorganisms harvest energy from plant material by means of complex enzymatic systems that efficiently degrade natural polymers. Perfluorooctanesulfonate (PFOS) is a compound that has wide applications with extreme persistence in the environment and the potential to bioaccumulate, and could induce adverse effects to ecosystems.

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.

Alternate Reductants with VB12 to Transform C8 and C6 Perfluoroalkyl Sulfonates: Limitations and Insights into Isomer-Specific Transformation Rates, Products and Pathways. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Background Biofuel production from lignocellulosic material is hampered by biomass recalcitrance towards enzymatic hydrolysis due to the compact architecture of the plant cell wall and the presence of lignin.

The LMS markedly reduced the elongation and tensile strength of these membranes. After 3 days of treatment with the LMS, the M w of polyethylene decreased from 242,000 to 28,300, and that of nylon-66 from 79,300 to 14,700. Perfluorooctanesulfonate Degrades in a Laccase-Mediator System.

For example, it has been found that laccase was able to degrade its unfavorable substrate, e.g., herbicide isoproturon, perfluorooctanesulfonate, and perfluorooctanoic acid using 1-hydroxybenzotriazole (HBT) and soybean meal as mediators (Luo et al., 2018a, 2018b; Zeng et al., 2017), respectively. Qi Luo's 15 research works with 239 citations and 1,481 reads, including: Perfluorooctanesulfonate Degrades in a Laccase-Mediator System Laccase-mediator reaction system is able to degrade perfluorooctanoic acid in soil. • Soybean meal can serve as a cost-effective natural mediator of laccase. • PFOA degradation products in soil are partially fluorinated organic compounds.
