Biological resistance of didecyl dimethyl ammonium tetrafluoroborate (DBF)-treated wood in soil-bed and Basidiomycetes tests
2006 - IRG/WP 06-30393
This study evaluated the decay resistance of treated wood with a new quaternary ammonia compound, didecyl dimethyl ammonium tetrafluoroborate (DBF) in laboratory soil bed and Basidiomycetes tests. Treated sugi sapwood specimens with DBF at various concentration levels were first subjected to soil bed tests using two types of soil. The specimens subjected to soil bed tests were then used for Basidi...

Optimization of oxalic acid production for bioleaching of metal components from CCA-treated wood by an unknown Polyporales sp. KUC8959
2010 - IRG/WP 10-50266
A brown-rot fungus, an unknown Polyporales sp. KUC8959, has recently been identified and proven as a prominent fungal species for bioremediation of CCA-treated wood wastes in our Lab. The fungus produced a larger amount of oxalic acid than other fungi tested, and removed 90 % or more of chromium, copper and arsenic from CCA-treated wood sawdust through bioleaching process. The bioleaching process ...
