Research Progress and Application of Prokaryotic Laccase

open access: yesShipin gongye ke-ji, 2023
A variety of phenolic and non-phenolic substrates can be oxidized by laccase using molecular oxygen as an auxiliary substrate. Due to the fact that laccase produces only water as a by-product, laccase is considered a "green tool enzyme" because it is ...

Kinetics of the reduction of metalloproteins by chromous ion [PDF]

open access: yes, 1972
The reduction of Cu(330) in Rhus vernicifera laccase by chromous ion is 30% faster than reduction of Cu(614) at room temperature [pH 4.8, µ = 0.1 (NaCl)], and two parallel first-order paths, attributed to heterogeneity of the protein, are observed at ...

Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

open access: yesAdvanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Degradation of phenolic inhibitors by laccase immobilized on tannic acid/polyethylenimine modified magnetic nanoparticles

open access: yesResults in Engineering, 2022
Magnetic Fe3O4 nanoparticles were successfully functionalized with the low-cost mussel-inspired tannic acid (TA)/polyethylenimine (PEI) under mild conditions and then activated with glutaraldehyde (GA) to covalently immobilize laccase for degradation of ...

Degradation of pesticides by the ligninolytic enzyme Laccase : optimisation of in vitro conditions, immobilisation and screening for natural mediators [PDF]

open access: yes, 2013
Pesticides are widely used in many industries but the majority reaches non-target organisms or locations through point or diffuse sources. Understanding conditions for their degradation is therefore important.

Cellulose oxidation by Laccase-TEMPO treatments [PDF]

open access: yes, 2017
In this work, laccase-TEMPO (Lac-T) treatments were applied to bleached commercial dissolving pulp in order to introduce carbonyl and carboxyl groups, which were found to improve dry and wet strength-related properties.
