"Fungi are proficient molecular disassemblers breaking down long chained toxins into simpler less toxic chemicals. They remove heavy metals from land by channeling them to fruit bodies for removal. they essentially use and digest these toxins as nutrients. Mycelial enzymes can decompose some of the most resistant materials made by humans or nature, because many of the bonds that hold plant material together are similar to the bonds found in petroleum products including diesal, oil, and many herbicides and pesticides."
