Context
In natural ecosystems, filamentous fungi are specialised in breaking down recalcitrant polymers—especially lignin—and certain species are documented to degrade PAHs through ligninolytic enzymes with broad substrate range (e.g. laccase, manganese peroxidase, lignin peroxidase). Nonetheless, only a handful of studies address their effectiveness against complex PAH blends such as creosote, and no commercial or industrial‑scale mycological remediation or valorisation process for creosote‑impregnated timber has yet been implemented.
Objectives
The exploratory project CLEANWOOD aims to capitalise on the complementary expertise of CRITT Bois and UMR BBF to investigate the feasibility of a fungal‑diversity‑based method for treating creosote‑impregnated timber.
Expected results
Thirty fungal strains will be screened for their ability to grow on and degrade creosote from two model timber substrates (one hardwood and one softwood), using samples sourced from industrial creosote‑treated wood waste. The results will then be used to explore novel valorisation pathways for creosote‑impregnated timber.
