Organic materials inoculated with the fungi are mechanically mixed into the contaminated soil.
Using enzymes normally produced for wood degradation as well as other enzyme systems, the fungi break down soil contaminants. Moisture control is needed and temperature and aeration may be important. This system was designed to treat soil contaminated with chemicals found in the wood preserving industry. These include chlorinated organics and polynuclear aromatic hydrocarbons. A SITE demonstration was initiated in September 1991 at the Wood Preserving site in Brookhaven, Mississippi.
