Improved laccase production by Trametes versicolor using Copper-Glycyl-L-Histidyl-L-Lysine as a novel and high-efficient inducer

Frontiers in Bioengineering and Biotechnology, 2023
A highly efficient strategy using Copper-Glycyl-L-Histidyl-L-Lysine (GHK-Cu) as a novel inducer was developed to enhance laccase production by Trametes versicolor.

Potential Degradation and Kinetics of Melanoidin by Using Laccase from White Rot Fungus

Applied Environmental Research, 2020
This study was attempted to use laccase extracted from white rot fungus to remove melanoidin in the ethanol production wastewater. The isolated fungus producing the highest laccase was identified as Megaspororia sp.

Oxidation of phenols by laccase and laccase-mediator systems. [PDF]

European journal of biochemistry, 2002
To investigate how solubility and steric issues affect the laccase-catalysed oxidation of phenols, a series of oligomeric polyphenol compounds, having increasing size and decreasing solubility in water, was incubated with laccase. The extent of substrate conversion, and the nature of the products formed in buffered aqueous solutions, were compared to ...

An evidence of laccases in archaea [PDF]

Indian Journal of Microbiology, 2009
Laccases (benzenediol:oxygen oxidoreductase, EC 1.10.3.2) are a diverse group of multicopper oxidases that catalyze the oxidation of a variety of aromatic compounds. Here we present evidence for distribution of laccases among archaea and their probable functions.

Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

Angewandte Chemie, EarlyView.
1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...

Evolutionary Relationships Between the Laccase Genes of Polyporales: Orthology-Based Classification of Laccase Isozymes and Functional Insight From Trametes hirsuta

Frontiers in Microbiology, 2019
Laccase is one of the oldest known and intensively studied fungal enzymes capable of oxidizing recalcitrant lignin-resembling phenolic compounds. It is currently well established that fungal genomes almost always contain several non-allelic copies of ...

Optimization and efficacy studies of Laccase immobilized on Zein-Polyvinyl pyrrolidone nano fibrous membrane in decolorization of Acid Red 1

Water Science and Technology, 2021
Azo dyes are widely used in textile industries. A significant portion of these recalcitrant dyes are being discharged to the natural waters. Due to their low biodegradability they pose serious pollution problems if untreated.

Gel-Based Purification and Biochemical Study of Laccase Isozymes from Ganoderma sp. and Its Role in Enhanced Cotton Callogenesis

Frontiers in Microbiology, 2017
Basidiomycetous fungi, Ganoderma lucidum MDU-7 and Ganoderma sp. kk-02 secreted multiple laccase isozymes under diverse growth condition. Aromatic compounds and metal salts were also found to regulate the differential expression of laccase isozymes from ...

Research Progress and Application of Prokaryotic Laccase

Shipin 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 ...

Purification and characterization of laccase from Pleurotus tuber-regium and its application in dye decolourization

BioTechnologia, 2019
Pleurotus tuber-regium is a unique sclerotium-forming white rot fungus. It is edible and has medicinal value and a high potentials of application in various industries. However, to date, there is no information on the production of laccase by this fungus,
