Inducing laccase activity in white rot fungi using copper ions and improving the efficiency of azo dye treatment with electricity generation using microbial fuel cells.

Chemosphere, 2019
This work presents a white rot fungus-microbial fuel cell (WRF-MFC) that uses WRF that is grown at its cathode. Adding Cu2+ to the fungi-containing solid medium stimulated WRF-secreting laccase, which catalyzed the redox reaction in the MFC and thereby ...

Automated chromatographic laccase-mediator-system activity assay

Analytical and Bioanalytical Chemistry, 2017
To study the interaction of laccases, mediators, and substrates in laccase-mediator systems (LMS), an on-line measurement was developed using high performance anion exchange chromatography equipped with a CarboPac™ PA 100 column coupled to pulsed amperometric detection (HPAEC-PAD). The developed method was optimized for overall chromatographic run time

Screening Metagenomic Libraries for Laccase Activities

2010
Laccases are multi-copper oxidoreductases (benzenediol:oxygen oxidoreductases, EC 1.10.3.2) able to oxidise a wide variety of phenolic and non-phenolic compounds. They are useful enzymes for a variety of applications, including bioremediation and craft pulp bio-bleaching as the most significant ones.

Fungal laccase: properties and activity on lignin

Journal of Basic Microbiology, 2001
The sources of ligninocellulose that occur in various forms in nature are so vast that they can only be compared to those of water. The results of several, more recent experiments showed that laccase probably possesses the big ability for "lignin-barrier" breakdown of ligninocellulose.

Mechanism of the salt activation of laccase Lac15

Biochemical and Biophysical Research Communications, 2020
Laccases (benzenediol: oxygen oxidoreductases, EC1.10.3.2) can oxidize various substrates, and those which are tolerant to and even activated by salts have attracted a lot of attention due to their application potential in certain industries. The mechanism of the salt activation of laccases is awaiting to be elucidated yet.

Catalytic activity of laccase hosted in reversed micelles

Journal of Bioscience and Bioengineering, 2001
Nanostructured reversed micelles induce a high laccase activity in organic solvents, because enzymes can maintain their highly dimensional structure in water pools of reversed micelles [RMs]. Laccase attracts considerable attention as a novel industrial enzyme due to its high capability to catalyze the oxidation of aromatic compounds.

Spore cells from BPA degrading bacteria Bacillus sp. GZB displaying high laccase activity and stability for BPA degradation.

Science of the Total Environment, 2018
Laccase has been applied extensively as a biocatalyst to remove different organic pollutants. This study characterized a spore-laccase from the bisphenol A (BPA)-degrading strain Bacillus sp. GZB.

Laccase activity in Sphagnum-dominated peatland: A study based on a novel measurement of delay dynamics (MDD) for determining laccase activity

Soil Biology and Biochemistry, 2019
The large reservoir of organic carbon in peatland is essential for the global carbon cycle. Laccase, probably the largest class of phenol oxidases in soil, plays an important role in the primary degradation of recalcitrant polyphenolic compounds. However,

Laccase activity of forest litter

Soil Biology and Biochemistry, 1999
Abstract Laccases are blue-copper enzymatic proteins involved in the transformation of polyphenolic compounds, such as lignin, into forest litter. A method to measure their activity was developed using an evergreen oak litter as a model system. We considered factors that affect the extraction of these enzymes and the measurement of their activity ...
