S prispevkom želimo predstaviti glavne rezultate in povzetek znanstvenih dognanj, do katerih smo prišli z dvema nacionalnima podoktorskima projektoma ob podpori takratnega Ministrstva za izobraževanje, znanost in šport Republike Slovenije (MIZŠ) ter Javne agencije za znanstvenoraziskovalno in inovacijsko dejavnost Republike Slovenije (ARIS). Analizirali smo biorafinerijski potencial manjvrednega lesa rdečega bora (Pinus sylvestris L.) in robinije (Robinia pseudoacacia L.) za ekstrakcijo naravnih bioaktivnih spojin. Les grč in jedrovine smo uporabili kot biomaso za ekstrakcijo polifenolnih ekstraktivov, ki smo jih nato uporabili v naravno osnovanih pripravkih za zaščito lesa. Rezultati so pokazali, da hidrofilni ekstraktivi grč bora in jedrovine robinije zavirajo glivni razkroj lesa in imajo velik potencial kot biocidne komponente in antioksidanti v naravno osnovanih zaščitnih pripravkih. Nadaljnje raziskave antioksidativnih in protiglivnih lastnosti ekstraktivov lesa in skorje so v teku.

• Title: Biorefinery potential of low-value scots pine (Pinus sylvestris L.) and black locust (Robinia pseudoacacia L.) wood for the extraction of natural bioactive compounds for wood preservation

Abstract

This article presents the key results and scientific findings from two national postdoctoral research projects supported by the Ministry of Education, Science and Sport of the Republic of Slovenia (MIZŠ) and the Slovenian Research and Innovation Agency (ARIS). We analyzed the biorefinery potential of low-value Scots pine (Pinus sylvestris L.) and black locust (Robinia pseudoacacia L.) wood for the extraction of natural bioactive compounds. Knotwood and heartwood were used as biomass for extracting polyphenolic compounds, which were subsequently applied in bio-based wood preservatives. The results showed that hydrophilic extractives from Scots pine knotwood and black locust heartwood inhibit fungal decay and demonstrate strong potential as biocidal components and antioxidants in natural wood protection formulations. Further research on the antioxidant and antifungal properties of wood and bark extractives is ongoing.
