This research focused on optimizing the extraction of an important industrial enzyme called filter paperase from rice husk using a fungal fermentation process. The findings are significant for making enzyme production more sustainable and cost-effective. Impacts on everyday life: • Enables more efficient use of agricultural waste like rice husk • Helps reduce production costs of industrial enzymes used in paper, textile and biofuel industries • Contributes to more sustainable and environmentally-friendly manufacturing processes • Could lead to cheaper consumer products that rely on these enzymes • Demonstrates ways to add value to agricultural waste materials
