Rapid depolymerization of cellulose occurs shortly after brown-rot fungi colonize wood. The chemical agent responsible for this initial depolymerization is most likely a low molecular weight compound (Cowling, 1961; Cowling and Brown, 1969) that diffuses through the crystalline microfibrils of cellulose, degrading the amorphous non-crystalline regions (Cowling and Brown, 1969; Highley, Palmer, Murmanis, 1983). It is important to identify the depolymerizing agent(s) produced by brown-rot fungi, because such information could serve as a foundation for the development of new methods to prevent wood decay.
