20.500.12556/DiRROS-7255 Translokacija bakra iz zaščitenega lesa, izpostavljenega glivam razkrojevalkam lesa Copper translocation from preserved wood exposed to wood decay fungi Na področju zaščite lesa se v zadnjem času pojavljajo na baker odporni sevi gliv, kar v praksi predstavlja velik problem. Tolerantne glive ogrožajo zaščiten les v uporabi z običajno trajnostjo nad 30 let, saj les okužen s tolerantnimi sevi gliv lahko propade že v nekaj letih. Mehanizmi tolerantnosti še niso povsem pojasneni. Velik pomen se pripisuje oksalni kislini, ki jo intenzivno tvorijo tolerantne glive. Z laboratorijskimi poskusismo ugotovili, da je poleg tega mehanizma pomemben tudi aktivni transport bakra v micelij gliv. Pri glivah, ki ne izločajo oksalne kisline, jetranslokacija bakra povzročena z difuzijo Copper tolerance by wood decay fungi is one of the most important problems in the field of wood preservation. These fungi are potential danger for preserved wood in use, wood with expected lifetime of 30 years. Although, the nature of the fungal tolerance is still not completely understood. The resistance of some species of wood decay fungi to copper has been connected to their production of copious amounts of oxalic acid. However, oxalic acid production is not the only factor responsible for this phenomenon. Laboratory experiments showed that one other important mechanism is active copper transport of copper tolerant fungi and diffusion of copper by intolerant ones zaščita lesa tolerantnost na baker oksalna kislina Antrodia vaillantii wood preservation copper based preservatives copper tolerance oxalic acid true false true Slovenski jezik Slovenski jezik Neznano 2017-07-12 09:10:50 2017-07-12 09:10:50 2022-08-12 13:30:14 0000-00-00 00:00:00 2002 0 0 str. 159-171 Vol. 67 2002 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*841 0351-3114 URN:NBN:SI:doc-DVX5JGDG 910985 6206978 zbgl-67-5.pdf zbgl-67-5.pdf 1 102A53B52E01B1D9CD662A7BB111D584 da677cdeb2ad2d56208408e07d26318535ccbcb8dbabc1fde5bae6bf9c093dd7 f428dffa-17b4-11ed-b6b8-001a4af901a5 20.500.12556/dirros/24dcaa89-9f23-4996-a319-ac63089b783c https://dirros.openscience.si/Dokument.php?lang=slv&id=9100 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
