Oyster mushrooms (Pleurotus ostreatus) grown on food waste–based substrates contained nearly twice as much ergothioneine, a potent antioxidant, compared to those grown on sawdust. Adding animal-derived kitchen waste increased both yield and ergothioneine levels. Blue LED light during cultivation boosted ergothioneine even further. In hydroponic tests, plants absorbed and stored ergothioneine from the leftover mushroom substrate.
