Biodegradation potential and ligninolytic enzyme activity of two locally isolated Panus tigrinus strains on selected agro-industrial wastes

Journal of Environmental Management, 2013
The degradation potential and ligninolytic enzyme production of two isolated Panus tigrinus strains (M609RQY and M109RQY) were evaluated in this study.

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.

Bisphenol A degradation in water by ligninolytic enzymes

Chemosphere, 2013
Many endocrine disruptor compounds, such as bisphenol A (BPA) are used today and released into the environment at low doses but they are barely degraded in wastewater treatment plants. One of the potential alternatives to effectively degrade endocrine disruptor compounds is based on the use of the oxidative action of extracellular fungal enzymes.

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

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 ...
