abstract = "The effect of FeCl3 (Fe3+), hydrogen peroxide (H2O2), a low molecular weight compound (2,3-Dihydroxybenzoic acid), and oxalic acid on wood were tested in a study designed to mimic wood degradationby brown rot fungi. Previous studies suggest that these components are involved in the early stages of brownrot decay where they catalyze the formation of hydroxyl radicals through the Fenton reaction or relatedmechanisms. However, the separate and combined effects of these individual chemical components on woodhave not been thoroughly investigated.Tests were conducted in Erlenmeyer flasks containing 50 ml of 40 mM acetate buffer (pH 4.5), white pinewood powder and varying combinations of the chemicals previously mentioned. Changes in cellulosecrystallinity were analyzed by X-ray diffraction using a ¿-2¿ scan. Findings suggest that iron, H2O2, chelatorsand oxalic acid may affect over all crystallinity and crystallite size. Understanding how these chemicals modifywood will facilitate characterization of the mechanisms involved in wood biodegradation by brown rot fungi.",
