Textile factories produce large amounts of colored wastewater containing harmful dyes like Reactive Black 5. Researchers optimized an enzyme-based treatment using laccase from a fungus called Coriolopsis gallica to remove these dyes from water. By carefully balancing enzyme concentration, pH, temperature, and a chemical booster called HBT, they achieved 82% dye removal in just 2 hours, offering a cleaner and more environmentally friendly alternative to traditional chemical treatments.
