In recent years a considerable amount of data have accumulated concerning the principal enzymes involved in wood decay by white‐rot fungi and about their biochemical mechanism of action. Various strains of fungi and their mutants having different enzyme production were selected and the patterns of degradation resulting from their action on wood were examined by transmission electron microscopy. A correlation between the nature of the enzymes and the micromorphology of degradation was tentatively established based on a comparison between the respective patterns created by a wild‐type strain and metabolic mutants in which a known activity was either enhanced or repressed. Results are illustrated with Phanerochaete chrysosporium, Dichomitus squalens and Phlebia radiata . In particular, the strong ability of manganese peroxidase and laccase to perform defibrillation of cellulose microfibrils is evidenced.
