Fungus, brown rot

Fomitopsis pinicola (Sw.) P. Karst.

Red-belted conk

A brown-rot fungus of conifer forests. It is among the brown-rot species most able to degrade DDT in culture. A species of the same genus, F. palustris, has been used to extract copper, chromium and arsenic from CCA-treated wood through the oxalic acid it produces.

Contaminants

ContaminantEvidenceWhat was shown
DDT and breakdown productslaboratory

Of 12 brown-rot species tested in potato dextrose broth, F. pinicola is one of the three (with Gloeophyllum trabeum and Daedalea dickinsii) showing a high ability to degrade DDT.

Arseniclaboratory

Data for Fomitopsis palustris: CCA-treated wood sawdust placed in the fermentation broth together with the fungal inoculum; 98% of arsenic, 92% of chromium and 96% of copper removed. This is biological acid leaching of a waste, not soil treatment.

Chromiumlaboratory

Fomitopsis palustris, same process: 92% of chromium removed from CCA-treated wood sawdust.

Copperlaboratory

Fomitopsis palustris, same process: 96% of copper removed from CCA-treated wood sawdust.

Limits

For F. pinicola the DDT result is a liquid-culture screening with no percentages in the abstract consulted. The CCA wood results belong to another species of the genus and to a fermenter: the metals move into an acidic liquid that then needs treatment. No field trial was found.
