Physicochemical Characterization of Acid-Treated Nanocrystal Cellulose and Amorphous Cellulose from Bamboo Sawdust

Sustainable Innovation: Fabrication and Characterization of Mycelium-Based Green Composites for Modern Interior Materials Using Agro-Industrial Wastes and Different Species of Fungi

“…First, this study found an inverse relationship between the density of MBCs and their water absorption ability, aligning findings from prior studies, indicating a decrease in water absorption capacity with an increase in composite density [ 15 ]. Second, variations in water absorption abilities were linked to differences in the chemical components of the composites, with bamboo sawdust (40.0–47.7% dry mass basis) containing a higher cellulose content than corn pericarp (15.3–22.5% dry mass basis), influencing the high-water absorption ability observed in this investigation [ 16 , 45 , 46 , 47 , 48 , 49 ]. This characteristic is often associated with a higher cellulose component, indicating a larger number of accessible hydroxyl groups [ 16 , 41 , 50 ].…”

“…Our research revealed distinct thermal degradation behaviors in MBCs made from bamboo sawdust and corn pericarp, likely associated with the chemical composition of the substrates. Typically, bamboo sawdust has an estimated dry mass basis composition of 40 to 47.7% cellulose, 21.9 to 31% hemicellulose, and 21 to 24.9% lignin, while corn pericarp consists of 15.3 to 22.5% cellulose, 23.7 to 40.4% hemicellulose, and 2.9 to 4.7% lignin on a dry mass basis [ 45 , 46 , 47 , 48 , 49 ], potentially impacting their degradation behaviors. Simultaneously, the weight loss of both pure substrates was slower than that of colonized substrates, indicating that fungal colonization renders the substrate more susceptible to thermal degeneration [ 24 ].…”
