Title: Hazardous waste treatment using fungus enters marketplace

Abstract

When the announcement was made eight years ago that a common fungus had been found that could degrade a variety of environmental pollutants, the news stirred interest in the scientific community, the private sector, and the general public. Here was the promise of a new technology that might be effective and economical in treating hazardous waste, especially the most recalcitrant of toxic pollutants. Today, commercialization is beginning amid a mixture of optimism and skepticism. The organism in question is white rot fungus, or Phanerochaete chrysosporium, and it belongs to a family of woodrotting fungi common all over North America. The fungi secrete enzymes that break down lignin in wood to carbon dioxide and water--a process called mineralization. These lignin-degrading enzymes are not very discriminating, however. The white rot fungi have been shown to degrade such materials as DDT, the herbicide (2,4,5-trichlorophenoxy)acetic acid (2,4,5-T), 2,4,6-trinitrotoluene (TNT), pentachlorophenol (PCP), creosote, coal tars, and heavy fuels, in many cases mineralizing these pollutants to a significant extent.
