2016. Sorption of Perfluorooctanoic Acid, Perfluorooctane Sulfonate and Perfluoroheptanoic Acid on Granular Activated Carbon. 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. 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

Sources: Laccase, one of the most important enzymes in the food sector, is on very high demand these days because of its industrial applications as well as health benefits; thus all its sources are extensively studied and researched upon.It can be extracted from higher plants, fungi and as recently Laccase-Mediator Pretreatment of Wheat Straw Degrades Lignin and Improves Saccharification . By Jorge Rencoret, Antonio Pereira González, The purposes of this work are to study the ability of a laccase-mediator system to remove lignin improving saccharification, The continuous increase in the world energy and chemicals demand requires the development of sustainable alternatives to non-renewable sources of energy. Biomass facilities and biorefineries represent interesting options to gradually replace the present industry based on fossil fuels. Lignocellulose is the most promising feedstock to be used in biorefineries. 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.

Due to its complexity, the degradation of lignocellulosic waste is a great challenge for sustainable development. The generation of lignocellulosic waste from various agro-based industries indicated the magnitude of problems including pulp and paper mill (effluent 150–200m 3 /ton and solid 160–450kg/ton), sugarcane molasses-based distilleries (effluent 15lit/1 lit alcohol production and 7 2014-12-24 Perfluorooctanesulfonate Degrades in a Laccase-Mediator System journal, August 2018.

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.

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).
