Abstract

Different rates of wood decay and ligninolytic activity were found in wood decayed by various white-rot fungi. Chemical and ultrastructural analyses showed wood decayed by Coriolus versicolor consisted of a nonselective attack on all cell wall components. Lignin degradation was restricted to the cell wall adjacent to hyphae or around the circumference of cell lumina. Decay by Phellinus pini, Phlebia tremellosus, Poria medullapanis and Scytinostroma galactinum was selective for lignin degradation. Secondary walls were void of lignin and middle lamellae were extensively degraded. A diffuse attack on lignin occurred throughout all cell wall layers. Variation in ligninolytic activity was found among strains of Phanerochaete chrysosporium. Differences in weight loss as well as lignin and polysaccharide degradation were also found when wood of different coniferous and deciduous tree species was decayed by various white-rot fungi.
