Nanopowders Keep Toxic Metals Out of Cultivated Mushrooms

Nanopowders Keep Toxic Metals Out of Cultivated Mushrooms

Oyster mushroom, Button mushroom

What they found

Nanopowders in growing substrate trapped cadmium and lead so oyster and button mushrooms didn't absorb them.

By pairing edible mushrooms with engineered nanopowders, researchers created a targeted “directed mycosorption” system that pulls toxic metals out of the cultivation substrate. Species like oyster and button mushrooms still absorbed beneficial minerals such as magnesium and zinc, but nanopowders trapped harmful contaminants like cadmium and lead, preventing them from entering the mushrooms and dramatically improving food safety during cultivation.
