Background
Neurospora crassa is a type of filamentous fungus of the ascomycota typically found in bread. Rhizopus oryzae is another type of filamentous fungi of the mucoromycta that is typically found in soil and rotting vegetation. Neither of these fungi are toxic or pathogenic to humans, but have not been extensively studied for research purposes. Both of these fungi have an observed natural tendency to form films on still liquids, where the N. crassa films have a skin-like texture and elasticity, and the R. oryzae films have a soaked cotton texture. N. crassa is well-known to regularly undergo anastomosis, which links the mycelial network together. R. oryzae also undergoes anastomosis regularly, but to a lesser degree due to the differences in the properties of the film.
Current methods of producing faux leather materials using fungi work by gradually growing layers, or inoculating a solid substrate, but this can result in higher costs and slower processing speed.
Invention Description
Researchers at Arizona State University have developed a novel process for creating textile materials with tunable properties from filamentous fungi. The textiles can range in texture from similar to leather or paper, depending on the species of fungi used and the growth conditions. This method of production utilizes the natural tendency of filamentous fungi to form films on still liquids, in order to generate many mycelial mats concurrently. These mats can be layered to create materials and textiles of varying thickness, composition, and mechanical properties.
