Scientists have developed a new method to produce exceptionally strong mushroom-based materials by using dikaryotic strains of Schizophyllum commune instead of monokaryotic strains. These new materials achieved record-breaking strength of 47 MPa, making them stronger than existing mycelium materials while maintaining flexibility. The enhanced strength comes from differences in cell wall composition and lower expression of a specific gene that normally affects material density. This breakthrough could lead to improved fungal-based alternatives for leather and textiles.
