Mushroom Bioaccumulation: Current Perspectives and Future Research Needs

Sign up or log in to save this to your schedule and see who's attending!

Fungi are effective facilitators of chemical transport through ecosystems because of their vast mycelial networks and the ability to move large amounts of nutrients and pollutants from their environment into their mushroom fruiting bodies.  While there is clear evidence of the hyperaccumulation of certain nutrients and heavy metals in mushrooms, bioaccumulation is highly variable between different chemicals and species of fungi.  Additionally, for many organic pollutants, which are often the focus of mycoremediation discussions, very little data exists on the mushroom sequestration and in some cases there are not even established protocols for how to test for them.

            In this presentation we will cover the mycelial uptake and transport of chemicals from their environment to their fruiting bodies then review the current understanding, or lack of understanding of which minerals, nutrients, heavy metals, and organic pollutants are stored well in mushrooms.  The implications of this topic are wide reaching, from cultivating mineral fortified mushrooms to risks of foraging mushrooms in contaminated environments to ecological consequences of food web toxicity from mushroom hyperaccumulation.

            Can you safely eat that oyster mushroom growing out of the oil spill?  Where is the fungus taking those heavy metals?  Are wild mushrooms more nutritionally potent than cultivated ones?  We will explore these questions and more!
