摘要

Engineered living materials (ELMs) composed entirely of fungal cells offersignificant potential due to their functional properties such as self-assembly,sensing, and self-healing. Alongside rapid developments in the ELM field,there is significant and growing interest in mycelium materials, which aremade from the vegetative part of filamentous fungi, as a potential source ofadvanced functional materials. In order to advance the development of fungalELMs that utilize the organism’s ability to regenerate as self-repair, newmethods for controlling and optimizing mycelium materials are needed, aswell as a better understanding of the biological mechanisms behind regeneration.In this study, pure mycelium materials are fabricated for use as leathersubstitutes, and it is found that chlamydospores, thick-walled vegetative cellsformed at the hyphal tip, may be the key to the material’s self-healing properties.The results suggest that mycelium materials can survive in dry andoligotrophic environments, and self-healing is possible with minimal interventionafter a two-day recovery period. Finally, the study characterizes themechanical recovery and physical properties of damaged and healed samples,allowing for the first characterization of fungal ELMs.
