Structural Analysis of Fast-Growing Aspen Alkaline Peroxide Mechanical Pulp Lignin: A Post-Enzymatic Treatment

open access: yesBioResources, 2016
An enzymatic mild acidic hydrolysis was used to separate and purify residual lignin from alkaline peroxide mechanical pulp (APMP). Using the optimum conditions for the laccase treatment (pH 4.5, temperature 50 °C, lignin consistency of 1%, a reaction ...

Molecular and biochemical characterization of a new thermostable bacterial laccase from Meiothermus ruber DSM 1279 [PDF]

open access: yes, 2016
A new bacterial laccase gene (mrlac) fromMeiothermus ruberDSM 1279 was successfully overexpressed to produce a laccase (Mrlac) in soluble form inEscherichia coliduring simultaneous overexpression of a chaperone protein (GroEL/ES).

Degradation of Dyes by Fungi: A Bibliometric Study and Bibliographic Review

open access: yesEnvironmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT The degradation of dyes from textile effluents is considered a major challenge due to their high potential for environmental contamination and health risks due to their toxicity. In this sense, the use of fungi for the degradation of these compounds is reported in the literature as an ecological alternative with great potential.

Biocatalytic Synthesis of Diamondoid Diols by the Brown‐Rot Fungus Wolfiporia cocos

open access: yesChemBioChem, Volume 27, Issue 3, February 2026.
Wolfiporia cocos cultures were tested for CH‐oxidative activity using rigid diamondoid substrates. Adamantane derivatives gave typical diols similar to known chemical oxidations, while diamantane‐4‐ol showed unusual selectivity, forming rare 4,9‐ and 1,9‐diols.

Sustainable Pretreatment of Food Waste for Enhanced Bioethanol Production and Improved Waste Management: A Review

open access: yesFood Science &Nutrition, Volume 14, Issue 2, February 2026.
The graphical abstract illustrates the conversion of food waste biomass into bioethanol through integrated pretreatment strategies. Physical (mechanical, thermal, sonication), chemical (alkali, acidic, oxidative/ROS), and biological (fungal, bacterial, enzymatic) pretreatments enhance biomass breakdown.

Constitution and Properties of Laccase [PDF]

open access: yesNature, 1949
IT was shown that laccase, which had been inactivated by cyanide under certain conditions, could be almost completely re-activated by cupric ions, whereas other metals were ineffective1. Further evidence will be presented here to show that copper is an essential constituent of this enzyme. Laccase was purified by the method of D. Bertrand2,3.

Lignin Nanoparticles Containing Cobalt‐Cyanine Complexes: Potential Multifunctional Platforms for Photoacoustic Imaging and Photothermal Treatment of Bacterial Biofilms in Chronic Wounds

open access: yesMacromolecular Bioscience, Volume 26, Issue 2, February 2026.
CoPc is combined with a lignin‐based material to obtain NPs sensitive to NIR irradiation and capable of ROS scavenging. Through the NPs, mild photothermal therapy can be achieved to act against bacterial biofilms. ABSTRACT Chronic wounds (CWs) are characterized by persistent inflammation and bacterial biofilms, which hinder healing and contribute to ...
