20.500.12556/RUL-138105 Characterisation, recovery and activity of hydrophobic compounds in Norway spruce log soaking pit water could they be used in wood preservative formulations? Norway spruce log soaking water (SLSW) is considered a waste in the plywood and veneer industry but has not been characterised, and its possible uses remain unexplored. The purpose of this study is to characterise and test the possibility of using SLSW in wood preservative formulations. First, the SLSW was characterised, and the presence of carbohydrates in the log soaking water was reduced with a hydrophobic adsorbent to reduce the nutrient availability for fungi in the liquids. Then, the feasibility of using SLSW and the sugar free SLSW (denoted later as EHC solution) as wood preservatives was studied by testing their antifungal and antioxidant activities and performing a mini-block test against Schizophyllum commune, Trametes versicolor, Fibroporia vaillantii and Gloeophyllum trabeum. Several phenolic compounds were found in the SLSW. This water also had high antioxidant activity at 1000 mg/L before and after carbohydrate removal but no antifungal activity. Its impregnation in wood caused a slight reduction in mass loss of the Pinus sylvestris specimens but had no effect on the Fagus sylvatica specimens when exposed against Schizophyllum commune, Trametes versicolor, Fibroporia vaillantii and Gloeophyllum trabeum. The SLSW as a wood preservative is invalid, even after partial carbohydrate removal. However, due to the presence of wood constituents, SLSW could be a resource for other uses requiring high antioxidant activity but specific applications need further investigation. log soaking liquid wood degradation natural chemicals biorefning Pinus sylvestis Fagus sylvatica tekočina za namakanje hlodov ekstraktivi razgradnja lesa naravne kemikalije biorafiniranje true false true Angleški jezik Slovenski jezik Članek v reviji 2022-07-11 08:21:52 2022-07-11 08:21:58 2023-06-05 13:51:38 0000-00-00 00:00:00 2022 0 0 12 str. iss. 5 Vol. 13 2022 0000-00-00 Zaloznikova NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2022-01-01 630*8 1877-265X 10.1007/s12649-022-01676-2 92903683 https://link.springer.com/article/10.1007/s12649-022-01676-2 1 8b81621d-00e1-11ed-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=158311 RAZ_Barbero-Lopez_Aitor_2022.pdf RAZ_Barbero-Lopez_Aitor_2022.pdf 1 6F583FE1F75B90464FFB35C159DC0A70 7b32fc2fe384af106a4b27f563696b1b363b0d46234e29a112612729ea7a6a01 75c05954-00e3-11ed-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=158313 Biotehniška fakulteta 0 0 0
