Bread-Eating Fungi Exploited to Make Sustainable Textiles

The Spring 2022 National American Chemical Society (ACS) meeting held in San Diego, California, was a hybrid meeting that featured a wide range of science topics. The offerings showcased the vast diversity of the chemical sciences and the increasingly integrated nature of the projects. This post explores the potential for mushrooms to become a source of sustainable material. 

Mushrooms do have a leathery feel, but Akram Zamani took this to the extreme. Using Rhizopus delemar, a fungus usually found on decaying food, Zamani’s group fed it bread and harvested chitin and chitosan fibers from its cells. These fibers were then spun into strings for use as sutures or wound healing mats. Additionally, the jelly-like residue harvested from the cell walls of the fungi could be spread out and dried into sheets that feel and perform like paper and leather. While biobased replacement textiles are growing in popularity, most of the technology for producing them still relies on petroleum-based feedstocks. The major advantage of the fungal-based textile is the feedstock: food waste. Additionally, what often takes several days in a fermenter or by other fungi only requires about two days of fungal growth because the R. delemar is water based and grows much faster. This type of submerged cultivation is fast and environmentally friendly, turning food waste into value-added textiles.
