AbstractThe wood of common pine (Pinus sylvestris L.) was subjected to a controlled decay by two test fungi species that induced brown-rot Coniophora puteana (Schum.: Fr.) P. Karst. and whiterot (Trametes versicolor L.: Fr.) Pilát. wood decay. The effect of the fungi on cellulose chemical properties was examined. Cellulose depolimerization occurs from the start of fungal growth in the wood. During the white-rot decay the cellulose depolimerization rate is slower, as compared with the brown-rot decay. The low-molecular-weight carbohydrate content stays at a constant level, which is indicative of a uniform cellulose depolimerization process and the use of decomposition products by the fungi. In the brown-rot decay the cellulose depolimerization process is much faster, α-cellulose is produced in lesser amount, while the cellulose depolymerization products formed are low-molecular-weight carbohydrates.
