Impact of enological tannins on laccase activity
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.

The Role of Laccase from Zygomycetous Fungus Mortierella elasson in Humic Acids Degradation
Biochemical stability of soil humus is an important factor affecting soil quality. Fungi are among the most efficient decomposers of humic matter due to presence of oxidative enzymes, including phenoloxidase laccase. Production of laccase by zygomycetes,

Electrochemical Evaluation of Laccase Activity in Must
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.

Phenolic substrates for fluorometric detection of laccase activity [PDF]
A fluorometric procedure has been developed for detection and estimation of laccase activity in fungal broth cultures. Laccase solution was pretreated with catalase for 1 h at 37 degrees C and pH 5. Homovanillic acid was then added and the reaction mixture incubated for a further hour at 37 degrees C.

PEGylation Greatly Enhances Laccase Polymerase Activity [PDF]
AbstractLaccase catalyzes the oxidation and polymerization of phenolic compounds in the presence of oxygen. Herein, we report for the first time that a previous PEGylation of laccase enhances the polymerase activity 3‐fold compared with the reaction of the native enzyme, as confirmed by UV/Vis spectroscopy. The polymerization of catechol increased only

Laccase Activity as an Essential Factor in the Oligomerization of Rutin [PDF]
The enzyme-mediated polymerization of bioactive phenolic compounds, such as the flavonoid rutin, has gained interest due to the enhanced physico-chemical and biological properties of the products, which increases their potential application as a nutraceutical.
