The lignin contents of eucalypt samples after the whole laccase-mediator sequence were determined (as Klason lignin) and compared with their respective controls (Table 1).

Chemosphere 74, 216-223. [ Links ] 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 Perfluorooctanoic acid (PFOA) (conjugate base perfluorooctanoate) — also known colloquially as C8 — is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock.It is a product of health concern and subject to regulatory action and voluntary industrial phase-outs. – Extracellular systems to produce H 2O 2 (required for enzyme oxidation) • Lignin Peroxidase (LiP): degrades nonphenolic units up to 90%, uses veratryl alcohol as “mediator”, “real ligninase” => high E 0 (>1.4 V*) • Mn Peroxidase (MnP): generates Mn3+ as a diffusible oxidizer (chelated by … FRs pretreated with laccase or laccase-mediator The FRs were pretreated with laccases alone or with laccases in the presence of 1-hydroxybenzotriazole (HBT, Sigma Co., St. Louis, MO, USA) as a mediator.

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. 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).

Use of pesticides is usually related to overproduction of crops in order to overcome worldwide demand of food and alimentary safety. Nevertheless, pesticides are environmental persistent molecules, such as the organochlorine pesticides, which are often found in undesired places.

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.

The LMS markedly reduced the elongation and tensile strength of these membranes.

Jinyuan Hu, Kun Lu, Shipeng Dong, Qingguo Huang, Liang Mao. Inactivation of Laccase by the Attack of As (III) Reaction in Water. A double-layer permeable reactive barrier (DL-PRB) system was originally proposed for the study for inducing in situ ECHOR reactions. The DL-PRB system was comprised of an oxidant releasing material layer followed by a layer of quartz sands immobilized with humification enzymes. Pretreatment with laccase and a phenolic mediator degrades lignin and enhances saccharification of Eucalyptus feedstock.
