Interaction of cellulolytic enzymes with fungal cell wall polysaccharides
2025 - IRG/WP 25-11071
…and lignin polymers. Wood rotting fungi often form an extracellular matrix (ECM) during the decay process. The ECM is mainly composed of a polysaccharide mixture, including β-1,3-glucan and β-1,6-glucan, which may form a gel-like structure that facilitates adhesion to the wood cell wall. Previous studies have…
