Impact of enological tannins on laccase activity [PDF]
OENO One, 2019 Aims: The aim of this research was to determine and quantify the ability of enological tannins to reduce laccase activity and, consequently, to protect wine color against enzymatic browning and/or oxidasic haze.

Electrochemical Evaluation of Laccase Activity in Must
Chemosensors, 2020 As laccase (produced by Botrytis cinerea) can significantly alter the properties of wine, winemakers frequently use commercially available colorimetric kits and spectrophotometers to measure the activity of this enzyme in grapes, must and wine.

Extracellular laccase activity in Tetraploa aristata [PDF]
Biotechnology Letters, 2002 Tetraploa aristata CLPS 419 produced maximum extracellular laccase activity at over 9 mU ml−1 in shaking cultures supplemented with glucose and 3.5 mU ml−1 in sucrose-grown ones. Laccase activity did not exceed 0.7 mU ml−1 in stationary cultures with glucose and was not detected in similar cultures with sucrose or in ones grown on lignin.

A Fungal Ascorbate Oxidase with Unexpected Laccase Activity. [PDF]
Int J Mol Sci, 2020 Ascorbate oxidases are an enzyme group that has not been explored to a large extent. So far, mainly ascorbate oxidases from plants and only a few from fungi have been described. Although ascorbate oxidases belong to the well-studied enzyme family of multi-copper oxidases, their function is still unclear. In this study, Af_AO1, an enzyme from the fungus

Laccase Activity in Trichoderma virens
, 2011 Fungal laccases are involved in multiple functions, such as lignin degradation, pigments (melanin) synthesis and degradation, detoxification and pathogenesis. Furthermore, they are useful biocatalysts for several biotechnological applications.The laccase gene function was previously analysed in Trichoderma virens, an effective biocontrol agent: six ...

Laccase activity measurement by FTIR spectral fingerprinting
Enzyme and Microbial Technology, 2019 Laccases (EC 1.10.3.2) are enzymes known for their ability to catalyze the oxidation of phenolic compounds using molecular oxygen as the final electron acceptor. Laccase activity is commonly determined by monitoring spectrophotometric changes (absorbance) of the product or substrate during the enzymatic reaction. Fourier Transform Infrared Spectroscopy

A structural-chemical explanation of fungal laccase activity. [PDF]
Sci Rep, 2018 AbstractFungal laccases (EC 1.10.3.2) are multi-copper oxidases that oxidize a wide variety of substrates. Despite extensive studies, the molecular basis for their diverse activity is unclear. Notably, there is no current way to rationally predict the activity of a laccase toward a given substrate.

Copper increases laccase gene transcription and extracellular laccase activity in Pleurotus eryngii KS004. [PDF]
Braz J MicrobiolThe white-rot fungus Pleurotus eryngii secretes various laccases involved in the degradation of a wide range of chemical compounds. Since the laccase production is relatively low in fungi, many efforts have been focused on finding ways to increase it, so in this study, we investigated the effect of copper on the transcription of the pel3 laccase gene ...
