We want to learn from nature how to do more with Scandinavian wood resources. The two primary wood species in Norway are Norway spruce (47%) and Scots pine (33%). Brown rot fungi occur primarily on conifer wood and in the boreal forest. Early in the brown rot decay process, extensive depolymerization of the wood cell wall occurs, causing the wood to rapidly lose strength in comparison to the rate of wood metabolism. This causes challenges for wood in service but creates possibilities for developing technologies for biorefining.
Enzymes, which are a key tool for biomass depolymerization, cannot penetrate the intact wood cell walls. Brown-rot fungi possess unique mechanisms employing the use of small metabolites such as iron ions to selectively remove biomass components, thus creating much improved access to their enzymes. This mechanism can be exploited in biorefining, while on the other hand, it needs to be controlled to prevent fungal damage to wood in service.
Exploitation of this kind of chemistry in (industrial) biomass conversion has so far been of limited success, due to a lack of understanding of the reaction process and of the interplay between various enzyme types, metabolites and reaction conditions. Through the BioMim project, we will acquire new insights into how brown rot fungi degrade wood and these will be used to improve biorefining processes as well as wood protection.
Extensive exploitation of lignocellulosic biomass as a feedstock for a variety of products is the key to develop a viable bio-economy. However, the natural resistance of lignocellulosic biomass to chemical and biological deconstruction is a challenge that biorefineries have to overcome.

International research team seeks more efficient biomass refinement processes
Researchers from across the world, including from the Norwegian Institute of Bioeconomy Research (NIBIO), plan to mimic the chemistry of the brown rot fungus to improve biorefining processes.
Forskere og næringsliv omfavner skogens skadesopp
I bioøkonomien skal olje erstattes med fornybar biomasse, som trær. Men å bryte ned og hente ut godsakene fra ei gran eller furu, er en omstendelig prosess. Nå leter forskere fra Campus Ås i skogen etter svar: De vil vite hvordan brunråtesoppen effektivt gjør jobben ute i naturen.
