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

Environmental 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.

REUSE OF DECOLORIZED DYEING EFFLUENTS IN REPEATED DYEINGS

Annals of the University of Oradea: Fascicle of Textiles, Leatherwork, 2016
In this experimental work, the effluents of the reactive and disperse dyeings were reused in the next dyeing after the decolourization by ozone gas. Accordingly, the polyester woven samples were dyed with C.I. Disperse Yellow 160, C.I. Disperse Red 77 and C.I. Disperse Blue 79:1, and the cotton woven samples were dyed with C.I. Reactive Yellow 176, C.I.

Microbial decolorization of azo dyes by Proteus mirabilis

Journal of Industrial Microbiology and Biotechnology, 1999
A bacterium identified as Proteus mirabilis was isolated from acclimated sludge from a dyeing wastewater treatment plant. This strain rapidly decolorized a deep red azo dye solution (RED RBN). Features of the decolorizing process related to biodegradation and biosorption were also studied. Although P.

Phase Transformations, Microstructural Effects, and Photocatalytic Activity of Tungsten Trioxide‐Geopolymer Composites

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
 . ABSTRACT Water and air pollution are pervasive issues, impacting the majority of global citizens. In response, geopolymers functionalized with photocatalytic metal oxides have emerged as sustainable materials for environmental remediation. This study examines how the Si/Al molar ratio (1 and 2) and photocatalytic WO3 loading (WO3/Al molar ratios of ...
