Lignin-degrading white-rot fungus (phanerochaete chryso-sporium) degrades a broad spectrum of organopollutants, including chlorinated, lignin-derived by-products of the Kraft pulping process. White-rot fungus degrades aliphatic, aromatic, and heterocyclic compounds. Specifically, white-rot fungus has been shown to degrade indane, benzo(a)-pyrene, DDT, TCDD, and PCBs to innocuous end products. The studies performed, to date, suggest that the white-rot fungus may prove to be an extremely useful mi croorganism in the biological treatment of hazardous organic waste.

Note: Certain plants, such as specific strains of Brassica (mustards), accumulate heavy metals when growing in metal contaminated soils, forming the basis for a process called phytoremediation. These plants can accumulate up to 40% of their biomass as heavy metals, including lead [Atlas 1995].
