Comparative Evaluation of Mechanical and Physical Properties of Mycelium Composite Boards Made from Lentinus sajor-caju with Various Ratios of Corn Husk and Sawdust

Researchers developed biodegradable composite boards using mushroom mycelium (Lentinus sajor-caju) grown on agricultural waste like corn husks and sawdust. By adjusting the ratio of these materials and board thickness, they created boards with properties comparable to commercial softboards and acoustic panels. These eco-friendly boards could replace synthetic materials in construction and furniture, reducing waste and pollution while maintaining good mechanical strength and sound absorption properties.

Cross-linking impacts the physical properties of mycelium leather alternatives by targeting hydroxyl groups of polysaccharides and amino groups of proteins

Scientists developed a leather-like material made from mushroom mycelium by treating it with chemical cross-linkers similar to those used in traditional leather tanning. The best results came from using glutaraldehyde, which chemically bonded to the mycelium’s proteins and carbohydrates, creating a stronger and more durable material. While the mycelium leather now has comparable strength to conventional leather, it needs to be more flexible. This research offers a more environmentally sustainable alternative to animal leather.
