An acid-stable laccase from sclerotium rolfsii with potential for wool dye decolourization [PDF]

, 2003
The plant pathogen basidiomycete S. rolfsii secretes two laccases (SRL1 and SRL2) with molecular weights of 55 and 86 kDa, respectively. Laccase production was shown to be inducible by the addition of 2,5-xylidine to the cultural media.

Increasing laccase activity of white rot fungi by mutagenesis and treating papermaking wastewater

, 2018
The aim of the work was to apply ultraviolet mutagenesis on white rot fungus Pleurotus ostreatus for enhancement of laccase production. The mutant strain UV-6 with higher laccase activity was obtained by screening and the highest laccase activity was ...

Increasing Redox Potential, Redox Mediator Activity, and Stability in a Fungal Laccase by Computer-Guided Mutagenesis and Directed Evolution

ACS Catalysis, 2019
Fungal high-redox-potential laccases (HRPLs) are multicopper oxidases with a relaxed substrate specificity that is highly dependent on their binding affinity and redox potential of the T1Cu site (ET1). In this study, we combined computational design with

Host‐Induced Silencing of Rhizoctonia Solani 5‐Enolpyruvylshikimate‐3‐Phosphate Synthase Impairs Its Virulence in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sheath blight disease of rice caused by the fungal pathogen R. solani AG1‐IA remains a big threat to rice production worldwide. A limited genetic variation in rice for tolerance to this pathogen and little success in understanding how it defeats host defence are major reasons behind it.

Improvement of fire reaction and mould growth resistance of a new bio-based thermal insulation material [PDF]

, 2016
In the present paper, the performance of an innovative thermal insulation rigid board is evaluated in terms of fire behaviour and fungal resistance. The board is based on vegetal pith and a natural gum (corn pith and sodium alginate) and it is completely

Gallic Acid‐Responsive microRNAs Reprogram Lignification During Drought Acclimation Process in Spearmint

Plant Biotechnology Journal, EarlyView.
ABSTRACT Mentha spicata L. (spearmint) is a high‐value aromatic and medicinal species, whose productivity is strongly affected by water deficit. Nevertheless, the molecular mechanisms underlying drought acclimation in this mint remain largely unexplored. Thus, here, we investigated the microRNA‐mediated regulatory processes triggered in M.

Chemical Modification of Laccase from Aspergillus oryzae and its Application in OCC Pulp

BioResources, 2016
Laccase activity and stability were improved and modified through the interaction between laccase amino acid residues (e.g., amino groups (-NH2) and carboxyl groups (-COOH)) and the chemical reagents thiourea dioxide (TDO) and L-phenylalanine methyl ...

Synthetic dye decolorization by three sources of fungal laccase [PDF]

, 2012
Decolorization of six synthetic dyes using three sources of fungal laccase with the origin of Aspergillus oryzae, Trametes versicolor, and Paraconiothyrium variabile was investigated. Among them, the enzyme from P.

Induction of Apoptosis in MCF‐7 Breast Cancer Cells by Selenium Nanoparticles Synthesized With Laccase Enzyme Isolated From Pleurotus Floridanus

eFood, Volume 7, Issue 3, June 2026.
This study showed the first successful synthesis of selenium nanoparticles (SeNPs) using laccase purified from Pleurotus floridanus, offering an eco‐friendly and biocompatible replacement to conventional chemical methods. The biosynthesized SeNPs exhibited significant antiproliferative effects on MCF‐7 breast cancer cells, with cell cycle analysis ...
