What it is

The term "mycoremediation" describes the use of fungi — most often mycelium — to destroy or bind pollutants: petroleum products, pesticides, heavy metals, some plastics and synthetic dyes. The key idea is that the fungi's extracellular enzymes (laccases, peroxidases, cytochromes P450) can cleave complex organic molecules that are beyond bacteria's reach.

Main directions

Key research results

Among the most cited work are Paul Stamets's publications on petroleum degradation and on using mycelium for water filtration in ecosystems after spills. Independent laboratories have confirmed the ability of a number of species to degrade components of crude oil and some organochlorine pesticides.

There are also data showing that certain fungi can accumulate cadmium, lead and arsenic — used in experimental soil-cleanup schemes around former industrial zones.

Related species

Among the wood-decay fungi mentioned in the mycoremediation context and in Stamets's work — first of all agarikon (Laricifomes officinalis), which has a dedicated section in "Mycelium Running". The full species list is in the mushroom catalog.
