AI Technical Summary

Technical Problem

Existing mycelial composite materials rely on agricultural waste substrates, resulting in unstable material properties and difficulty in preparing dense, high-strength pure mycelial fiber materials. Furthermore, traditional methods are insufficient for the efficient, low-cost preparation and densification of pure mycelia.

Method used

A multi-stage cultivation route combining liquid static film formation, semi-solid thickening, and solid cultivation was adopted. Through four-dimensional environmental regulation of temperature, light, gas, and humidity, mycelial densification and solidification were induced, and independent pure mycelial fiber layers were obtained by peeling. These layers were then hot-pressed into high-performance biological mycelial skin materials.

Benefits of technology

It achieves high density and certain tensile strength in pure mycelial fiber materials, freeing them from substrate limitations. It is suitable for applications such as imitation leather materials and decorative finishes, and has high application value.

Abstract

The invention discloses a pure edible fungus mycelium fiber material as well as a preparation method and application thereof. The preparation method comprises the following steps: S1, activating a strain; s2, liquid static film forming; s3, thickening the semi-solid; s4, solid cultivation and environment-induced densification and solidification: peeling off the thickened mycelium layer, transferring into a solid cultivation environment containing a support carrier, and inducing the mycelium to densify and solidify to obtain a pure mycelium fiber compact layer; s5, stripping and post-processing; and S6, performing hot press molding to obtain the pure edible fungus mycelium fiber material. The limitation of agricultural waste substrates on material performance is thoroughly eliminated, and the prepared pure mycelium material is in a complete bacterial cortex form, is high in compactness, has certain tensile strength, can be used for preparing leather-imitating materials, decorative veneers and the like, and has relatively high application value.
