Perfluoroalkyls are stable, synthetic chemicals. Perfluoroalkyls are unique because they repel oil, grease, and water.The two perfluoroalkyls made in the largest amounts in the U.S. are perflurooctanoic acid and perfluorooctane sulfonic acid (PFOS).Perfluoroalkyls have been used in surface protection products such as carpet and clothing treatments and coating for paper and cardboard packaging.

Issue Date: September 2016. DOI: https://doi.org/10.1007/s12155-016-9745-z 2019-11-15 · 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. 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.

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

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).

The pretreatment was carried out in a 500-mL conical flask in a shaking incubator operating at 150 revolutions per min (rpm) and 50 °C. There are several production and purification strategies for laccase which are discussed below. 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.

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.

Mohammed Nasir, a, * Rokiah Hashim, a, * Othman Sulaiman, a Noor Afeefah Nordin, a Junidah Lamaming, a and Mohd Asim b In the last two decades, laccases have received much attention from researchers because of their specific ability to oxidize 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) feedstock, thus improving saccharification, and to analyze the chemical modifications produced in the whole material and especially in the recalcitrant lignin moiety.

compared. 2013-12-01 Natural fibres have a high potential as reinforcement of polymer matrices, as they combine a high specific strength and modulus with sustainable production and reasonable prices. Modifying the fibre surface is a common method to increase the adhesion and thereby enhance the mechanical properties of composites. In this study, a novel sustainable surface treatment is presented: the fungal enzyme Lignocellulosic biomass is a potential major resource for renewable energy production. 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. This study aims to overcome this barrier by combining two paradigms into a single system Decolourization and detoxification of textile industry wastewater by the laccase-mediator system. J. Hazard.
