This research demonstrates how to successfully grow the medicinal mushroom Oudemansiella radicata in artificial conditions using oak sawdust and rice bran. This is significant because this mushroom contains compounds that fight cancer and harmful plant fungi. The study provides the first successful cultivation method in Korea, opening doors for commercial production. Impacts on everyday life: • Makes it possible to produce beneficial medicinal mushrooms commercially rather than having to forage them in the wild • Could lead to more accessible and affordable natural cancer-fighting compounds • Provides farmers and mushroom growers with new crop opportunities • Helps preserve wild mushroom populations by reducing harvesting pressure • Enables consistent year-round production of mushrooms that normally only grow seasonally
