Chitin fungal cell wall

WebChitin is an integral part of the fungal cell wall and, together with β-1,3-glucan, plays a key role in maintaining cellular integrity and can confer structural rigidity during growth and morphogenesis (Corrêa et al., 2024). Chitin accounts for 10–20% of the dry weight of the cell wall of A. fumigatus and is of considerable inportance.

Current trends in fungal biosynthesis of chitin and chitosan

WebChitin. Chitin is a constituent of the cell walls of common soil fungi (e.g., Aspergillus and Penicillium), with from 3% to 25% of fungal biomass consisting of chitin on a dry-weight basis. Chitin is also added to soil as part of the exoskeletons of arthropods and crustaceans (Chapter 8). As a long-chain, linear biopolymer of N ...
