Prevention of brown-rot decay by chelators
1992 - IRG/WP 92-1540
In this work the brown-rot decay was shown to be prevented by chelating the endogenous metals existing in wood by using organic or inorganic chelators or iron-binding siderophores. The fungal growth and decaying ability were significantly decreased by the chelating treatments of the solid wood-based culture medium and pine wood pieces, respectively. The transition metals existing in native wood ar...

Non-enzymatic Gloeophyllum trabeum decay mechanisms: Further study
2001 - IRG/WP 01-10395
Information will be presented on the mechanisms involved in, and potential application of, non-enzymatic wood decay by brown rot decay fungi. Specifically, the hypothesized role of low molecular weight phenolate derivatives will be discussed in relation to non-enzymatic degradation of wood. The mechanism of binding of iron by cellulose, and binding and reduction of iron by fungal derivatives and m...

Lignin-copper, a new wood preservative without arsenic and chromium
1992 - IRG/WP 92-3702
A more environmentally sound treatment for wood with preservatives containing no arsenic or chromium, has been developed and studied on a laboratory scale. The method involves a first step impregnation with an aqueous solution containing modified, water-soluble kraft lignin followed by a second step involving impregnation with a copper salt solution to give fixation of the lignin into a water-inso...

Elimination of alternative explanations for the effect of iron on treated wood
1993 - IRG/WP 93-30006
Amounts of iron which had previously been found in stakes removed from ground contact reduced decay of untreated wood by four brown-rot fungi. This suggested that the effect of iron may be on the preservative. Analysis of the leachates from CCA- and ACA-treated wood blocks first exposed to rusting iron, then to a brown-rot fungus, showed that the increased decay found in the laboratory for wood ex...

Metal carboxylates for wood pest control
1996 - IRG/WP 96-30109
Metal carboxylates have been used as wood preservatives for more than fifty years. Predominantly salts of naphtenic acids have been commercially applied so far. They have water repellent as well as fungicidal and insecticidal properties. In the last years, metal carboxylates of saturated fatty acids were introduced. Fatty acids with 7-10 carbon atoms already have fungicidal activity by themselves....

EPR investigations of interactions between ammoniacal Cu(II) octanoate and wood
1996 - IRG/WP 96-30110
Ammoniacal solutions of copper(II) octanoate [ C u . h l f . 2 . r h l f.(O2CC7H15)4], interactions of these solutions with wood and wood components, and leaching of copper(II) octanoate from impregnated wood samples, have been studied by electron paramagnetic resonance (EPR) method. It is still not clear if in the Cu(II) octanoate - water - ammonia system, Cu(II) remains in a (copper(II) octanoat...
