Researchers developed an innovative biodegradable membrane containing mushroom fungus (Morchella esculenta) to clean textile dye-contaminated water. The membrane uses natural fungal enzymes called laccase to break down harmful dyes while also absorbing them, achieving 98.6% dye removal in 60 hours. This eco-friendly approach eliminates the need for toxic chemicals used in traditional water treatment and can be reused multiple times, making it promising for industrial textile wastewater treatment.
