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.

Ozonolysis of Lignin: From Extensive Degradation to Selective Ring‐Opening Oxidation

open access: yesChemSusChem, Volume 19, Issue 4, 25 February 2026.
Despite its potential as a renewable feedstock, lignin, a major component of plant cell walls and a by‐product of the pulp and paper industry, has long been underutilized. Historically, pulp mills employed ozonolysis, a powerful oxidative process, to delignify cellulosic fibers and break down lignin.
