This research demonstrates how mushroom fungi can be used to convert agricultural waste materials into valuable compounds with health benefits. The study shows that the fungus Pleurotus pulmonarius can grow on various agricultural wastes to produce beneficial molecules called exopolysaccharides. Impacts on everyday life: • Provides an environmentally friendly way to recycle agricultural waste • Produces natural compounds that can be used as food preservatives • Creates prebiotics that support beneficial gut bacteria • Generates antioxidants that could be used in health supplements • Demonstrates sustainable production of antimicrobial compounds
