Masson pine undergoes rapid degradation by brown-rot fungi, but how the fungus alters the microstructure of Masson pine cell wall is still unclear. In this study, Masson pine samples were incubated with Gloeophyllum trabeum to aid in characterizing changes in the crystalline structure of cellulose and chemical composition of wood in brown-rot decay. Fungal action resulted in an initial increase in wood cellulose crystallinity and crystallite width because of early removal of the more amorphous celluloses, followed by a decrease in crystallinity and crystallite size. All data suggest that hemic...
