ClearCatalytic and Physicochemical Evaluation of a TiO2/ZnO/Laccase Biocatalytic System: Application in the Decolorization of Azo and Anthraquinone Dyes
Researchers developed a biocatalytic system combining titanium dioxide, zinc oxide, and the enzyme laccase to break down textile dyes in wastewater. The system successfully decolorized two types of synthetic dyes used in fabric manufacturing. While not directly about microplastics, synthetic dye wastewater from textiles also carries microfibers, and treatments that address both problems together are environmentally valuable.
Eco-Friendly Biocatalysts: Laccase Applications, Innovations, and Future Directions in Environmental Remediation
This review examines how laccase enzymes, naturally produced by fungi and other organisms, can be used as eco-friendly biocatalysts for breaking down environmental pollutants.
