3. Results

The data set used for validation of the theoretical model contains data on fungal mass losses obtained from literature data on a series of thermally modified wood species with known elemental composition ([3], Figs. 3 and 4). The reported results were obtained from different test Basidiomycete species Poria placenta, Gloeophyllum trabeum and Coniophora puteana, three aggressive brown rot fungi, all showing similar trends. Five European wood species, Poplar, Beech, Ash, Pine and Fir, were analysed at 4 different thermal treatment levels, characterized by their relative thermal mass loss (0, 5, 10, and 15%) of oven-dried weight compared to untreated dry weight. The thermal modifications were performed at different temperatures ranging from 200 to 230 C, for several heating rates and heating durations, under atmospheric conditions with nitrogen as a shielding gas. The typical total duration time was between 10 and 24 h for all runs [3].
