In the current context of growing environmental awareness, the problems of high energy consumption, high pollution, and long degradation cycles of traditional materials have become increasingly prominent. For example, the energy consumption for plastic production reaches 80 - 100MJ/kg, and it takes 100 - 500 years to degrade. In sharp contrast, mycelium materials have emerged. They have low energy consumption, fast degradation, and their raw materials are derived from agricultural waste. Now, they have already shown their potential in the fashion field, and their broader application prospects are worthy of our in - depth exploration. Today, we will provide a relatively comprehensive overview of mycelium materials.

Basic Concepts and Characteristics of Mycelium Materials

1.1 Biological Definition of Mycelium

Mycelium is the vegetative growth part of fungi, composed of countless branched hyphae. Hyphae secrete enzymes to decompose organic substrates (such as lignin and cellulose), absorb nutrients, and form a network structure. This natural growth characteristic makes it a programmable biomaterial.

Degradability: It can be completely decomposed in 3 - 6 months in the natural environment, much faster than plastic (which takes hundreds of years).

Lightweight and High - Strength: The compressive strength reaches 0.5 MPa, and the density is only 0.1 - 0.3 g/cm³ (close to foamed plastics).

Fire - Resistance and Heat - Insulation: Some mycelium composites can withstand high temperatures of 300℃ after modification.

Plasticity: It can be molded into any shape through mold design to adapt to diverse application scenarios.

Production Processes and Technological Advances of Mycelium Materials

2.1 Core Production Processes

Substrate Pretreatment: Agricultural waste such as straw and wood chips are crushed and sterilized (by steam treatment or γ - ray irradiation).

Inoculation: Select white - rot fungi (such as Pleurotus ostreatus strains) or brown - rot fungi, with an inoculation amount of 5 - 10% (w/w).

Mycelium Cultivation: Cultivate at 25 - 30℃ and a humidity of 80 - 90% for 5 - 10 days to form a dense mycelium network.

Post - Treatment: Hot - pressing and shaping (70 - 90℃), drying (moisture content < 10%), or surface coating (water - proof, antibacterial).

Gene - Editing Technology: The CRISPR - Cas9 technology is used to enhance the enzyme - producing ability of mycelium, shortening the growth cycle by 30% (achievement of Bolt Threads in the United States).

3D - Printed Mycelium: Mix the mycelium suspension with nanocellulose and directly print complex structures (breakthrough of Utrecht University in the Netherlands).

Intelligent Fermentation System: AI real - time regulates the CO₂ concentration and temperature to improve the material uniformity (patented technology of the German BioFabrication Lab).

Degeneration of Strains: Continuous sub - culturing leads to a decrease in growth rate, and the mother strain needs to be updated every 6 months.

Cost Control: Currently, the production cost of mycelium materials per cubic meter is 200 - 300, and the goal is to reduce it to 50 (comparable to EPS foam).
