WebIn this study, a dual-chambered microbial fuel cell (MFC) was constructed to treat polyether wastewater for the first time. With laccase-modified cathode, the degradation rate of chemical oxygen demand (COD) in the wastewater from the cathode chamber achieves 68.1% at a pH of 4.0 within 24 h, 69.8% higher than that of unmodified carbon felt … WebAims: To select better performing laccase variants among the 2300 randomly mutated variants of Pleurotus ostreatus POXA1b laccase to develop improved laccase-based biocatalysts. Methods and results: Screening of collections of 2300 randomly mutated variants of POXA1b was performed by assaying activity towards the phenolic substrate …
Optimization of laccase production from Marasimus palmivorus
Weblaccase: [noun] a blue copper-containing oxidase occurring especially in the sap of lacquer trees and having an ability to produce lacquer from the sap and induce oxidation of … WebLaccase (EC 1.10.3.2. diphenol:oxygen oxidoreductase) has been known already since the 1880s when it was first described in the lacquer tree [3]. Laccase is a copper-containing … jenko fishing rip knocker
Laccase Properties, Physiological Functions, and Evolution
WebLaccases are abundant in microorganisms specialized in lignocellulose degradation, but the exact role of the enzymes in this process remains poorly understood. Laccases catalyze oxidation of lignin, initially producing a phenoxy radical. The heterogeneous lignin structure can stabilize these reactive radicals, but eventually, they dissipate by uncharacterized … WebIn this study, vanillin catalyzed by laccase was grafted into poplar wood to increase wood decay resistance and can remain in wood for longer period. The reaction system of vanillin, ABTS, laccase and phosphate buffer solution was impregnated into poplar wood using vacuum-pressure method, and reacted at 40 °C for 6 h. WebSep 6, 2024 · Respect to Nick's opinion, I suggest you to use guaiacole to be sure about the laccase activity. The color change of guaiacol is so clear if there is a few laccase in the medium due to its sensivity. lakme guntur
