Perfluorooctanesulfonate* PFOS 1763 -23 1 Perfluoroheptanesulfonate PFHpS 375-92-8 Degrades to some extent in the environment No Yes •Municipal systems >10,000 and selected smaller systems •Detected in ~4%, exceeded EPA LHAs in ~1.3% •High RLs and However, there has been little discussion of the reaction mechanisms for cleavage of model compounds with a non-phenolic β-O-4 lignin substructure by laccase–mediator couples. Because the β- O -4 substructure is the major interphenylpropane unit in lignin, elucidation of the degradation pathways for this structure is very important.

The use of laccase-mediator systems has since not focused on plastic, but on bioremediation of other compounds such as perfluoroctanesulfonate, carbamazepine, and non-steroidal anti-inflammatory drugs (NSAIDs) (Luo et al., 2018; Naghdi et al., 2018; Apriceno et al., 2019).

Environ Sci Technol 52:10617–10626. CAS Google Scholar Abstract. We investigated whether the laccase-mediator system (LMS) with 1-hydroxybenzotriazole (HBT) as a mediator could degrade high-molecular-weight polyethylene and nylon-66 membranes.

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.

Degradation of Perfluorooctanesulfonate by Reactive Electrochemical Membrane Composed of Magnéli Phase Titanium Suboxide. Perfluorooctanesulfonate Degrades in a Laccase-Mediator System. 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 purpose of this work is to study the ability of an industrially available laccase-mediator system to modify and remove lignin during pretreatment of wood (Eucalyptus globulus Summary Matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) was used to investigate the reaction products obtained by treatment of phenolic substances with the laccase-mediator system, consisting of the enzyme laccase and a low-molecular-weight substance, the so-called mediator.

23. Se hela listan på site.caes.uga.edu 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. The use of laccase-mediator systems has since not focused on plastic, but on bioremediation of other compounds such as perfluoroctanesulfonate, carbamazepine, and non-steroidal anti-inflammatory drugs (NSAIDs) (Luo et al., 2018; Naghdi et al., 2018; Apriceno et al., 2019).
