Ligninolytic enzyme complex ofArmillaria spp

Folia Microbiologica, 2000
Ten strains belonging to five species of European Armillaria (Fr.:Fr.) Staude were examined for their ability to produce laccase, lignin peroxidase, manganese-dependent peroxidase and manganese-independent peroxidase. No lignin peroxidase activity was observed in any of the strains.

Influence of Xenobiotics on Fungal Ligninolytic Enzymes

2021
White rot fungi (WRF) (belonging to the Basidiomycota family) are considered as the most efficient microorganisms to degrade lignin polymer through secretion of lignin-modifying enzymes such as oxidases (laccase) and peroxidases (lignin peroxidase and manganese peroxidase).

Extremophilic Ligninolytic Enzymes

2017
Extremophilic microorganisms have developed a variety of physiological strategies that help them to survive on different ecological niche such as extreme temperature, pH, salt concentration and pressure. It has been demonstrated that these microorganisms produce extracellular isoenzyme capable to degrade the ligninocellulosic waste and other related ...

Degradation of glyphosate and other pesticides by ligninolytic enzymes

Biodegradation, 2009
The ability of pure manganese peroxidase (MnP), laccase, lignin peroxidase (LiP) and horseradish peroxidase (HRP) to degrade the widely used herbicide glyphosate and other pesticides was studied in separate in vitro assays with addition of different mediators. Complete degradation of glyphosate was obtained with MnP, MnSO4 and Tween 80, with or without

PRODUCTION OF LIGNINOLYTIC ENZYMES BY SOLID-STATE FERMENTATION USINGPleurotus eryngii

Preparative Biochemistry and Biotechnology, 2012
Pleurotus eryngii (DC.) Gillet (MCC58) was investigated for its ability to produce various ligninolytic enzymes such as laccase (Lac), manganese peroxidase (MnP), aryl alcohol oxidase (AAO), and lignin peroxidase (LiP) by solid-state fermentation (SSF ...

Ligninolytic Enzymes of Endospore-Forming Bacillus aryabhattai BA03

Current Microbiology, 2020
In this work we investigated the enzymes produced by Bacillus aryabhattai BA03, particularly in those involved in ligninolytic activities such as laccases (Lac), lignin peroxidases (LiP) and Mn-dependent peroxidase (MnD-P). In this way, the maximal production of Lac (0.069 ± 0.000 U/mL) was obtained at pH 9, and 37 ºC after 72 h.

Structure and Action Mechanism of Ligninolytic Enzymes

Applied Biochemistry and Biotechnology, 2008
Lignin is the most abundant renewable source of aromatic polymer in nature, and its decomposition is indispensable for carbon recycling. It is chemically recalcitrant to breakdown by most organisms because of the complex, heterogeneous structure.

Production of Ligninolytic Enzymes by Phlebia Floridensis

World Journal of Microbiology and Biotechnology, 2005
The present work reports the production of laccase, lignin peroxidase and manganese peroxidase by the little studied white-rot fungus Phlebia floridensis under a variety of nutritional and physicochemical conditions. Among the different media and supplements the highest yields of laccase, lignin peroxidase and manganese peroxidase were recorded in the ...

Ligninolytic Enzymes in Environmental Management

2013
By producing lignocellulose-degrading enzymes, saprotrophic litter-decomposing Basidiomycetes can significantly contribute to the turnover of soil organic matter. The production of lignin- and polysaccharide-degrading enzymes helps in converting the waste litter into value-added compost.

Ligninolytic Enzymes of the White Rot Basidiomycete Trametes trogii

Acta Biotechnologica, 2001
The white rot fungus Trametes trogii strain BAFC 463 produced laccase, manganese peroxidase, lignin peroxidase and cellobiose dehydrogenase, as well as two hydrogen peroxide-producing activities: glucose oxidizing activity and glyoxal oxidase. In high-N (40 mM N) cultures, the titres of laccase, MnP and GLOX were 27 (6.55 U/ml), 45 (403.00 mU/ml) and 8
