Abstract

Introduction Although many basidiomycetes exhibit different types of cell wall attack, these fungi are able to degrade all cell wall components, but large variations can be found in the types of decay which they produced. Cellulose, hemicellulose and lignin can be degraded at different rates, or a preferential attack on lignin and hemicellulose can occur (Blanchette et al. 1987). A large number of white rot fungi were shown to selectively remove lignin from a variety of woods (Blanchette 1984; Blanchette and Reid 1986; Otjen and Blanchette 1986). Preferential lignin degradation can occur in localized areas of wood resulting in whitepocket rot or in larger, less restricted areas typical of decay with a mottle-rot appearance (Blanchette et al. 1985). Micromorphological studies of wood in advanced stages of delignification have demonstrated a loss of middle lamella from the cell walls and a defibration of the wood (Blanchette etal. 1985). Ultrastructural investigation of lignin loss from the cell walls of aspen and birch wood decayed by Phlebia tremellosa confirmed the extensive loss of lignin from the second4 To whom correspondence should be addressed.
