Summary

This research explored growing mushroom tissue (mycelium) on specially designed synthetic fiber mats to create new composite materials. The study shows how different types of fiber mats can influence how the mushroom tissue grows and develops, potentially leading to materials with unique properties. Impacts on everyday life: – Could lead to development of stronger, more sustainable filtering materials – May enable creation of new eco-friendly composite materials for various applications – Demonstrates potential for combining biological and synthetic materials in novel ways – Could contribute to more sustainable manufacturing processes – May help advance development of biodegradable materials

Background

Electrospinning technology has become increasingly popular for producing nanofiber mats, with applications in tissue engineering, regenerative medicine, and filtering. While nanofiber mats offer advantages like large surface-to-volume ratio and high porosity, their mechanical weakness limits their use. One potential solution is combining nanofiber mats with biological stabilizing structures like fungal mycelium.

Objective

To investigate whether modified polyacrylonitrile (PAN) nanofiber mats are suitable substrates for fungal mycelium growth, to increase growth rates, and to examine how different substrate modifications affect mycelium fiber morphologies. The study aimed to explore the possibility of creating bio-based composites using electrospun substrates.

Results

The mycelium successfully grew on all nanofiber mat variants, showing different morphologies depending on the substrate. Growth was denser on nanofiber mats compared to pure agar. Straight, even mycelium fibers were observed on stabilized PAN, while more chaotic, irregularly bent fibers grew on PAN/poloxamer. The mycelium grew through the nanofiber mats, forming composites. Stabilization and carbonization of the composites was achieved, though this process affected mycelium morphology.

Conclusion

The study demonstrated that PAN nanofiber mats can serve as effective substrates for Pleurotus ostreatus mycelium growth, with substrate composition influencing mycelium morphology. The ability to create stabilized and carbonized composites opens new possibilities for developing materials with tailored properties for various applications.
