Difference of wood decay manner between brown-rot species
2019 - IRG/WP 19-10938
Wood blocks (Cryptomeria japonica) which were decayed by a Polyporales white-rot fungus (Trametes versicolor) and brown-rot fungi (Fomitopsis palustris, F. pinicola, and Wolfiporia cocos), respectively, were analyzed by X-ray diffraction and infrared spectroscopic methods followed by multivariate analysis. In the analyses, the differences in the cellulose crystallinities and infrared spectral patt...

Morphological observation of wood at the early stages of decay in brown rot and white rot
2023 - IRG/WP 23-11020
Wood rotting fungi, the fungal species causing biodeterioration for wood building, are generally classified into white-rot, brown-rot and soft-rot fungi based on their decay modes. Since white-rot and brown-rot fungi are known to reduce wood strength significantly, it is important to clarify the mechanisms of their wood degradation. White-rot fungi reduce wood strength as the decay progress and de...
