Mechanical properties of dense mycelium-bound composites under accelerated tropical weathering conditions

mycolabadmin

Researchers developed a sustainable alternative to traditional particleboard using mushroom mycelium (fungal root structure) grown on agricultural waste like sawdust and palm fruit remnants. When exposed to hot, humid tropical conditions for 35 days, the material’s strength decreased significantly, but applying a protective oil coating helped preserve tensile strength. The study shows that with improvements to manufacturing processes, these mushroom-based composites could replace harmful formaldehyde-based particleboards in indoor construction.

Tailoring the Mechanical Properties of Fungal Mycelium Mats with Material Extrusion Additive Manufacturing of PHBH and PLA Biopolymers

mycolabadmin

Researchers have developed a novel method to make mushroom-based materials stronger by coating them with biodegradable plastics using 3D printing technology. This approach combines fungal mycelium from Fomes fomentarius with eco-friendly polymers to create composites that are significantly stronger than plain mycelium while remaining fully compostable. The resulting materials could be used for flexible devices, interior design, and other applications where both strength and environmental sustainability are important.

Strongest untreated mycelium materials produced by Schizophyllum commune dikaryons

Researchers found that mushroom mycelium grown from dikaryotic strains (with two nuclei) produces stronger, stiffer materials than traditional monokaryon strains used in mycelium-based products. These dikaryotic materials show tensile strength values comparable to some polymers, making them promising for creating sustainable alternatives to leather and textiles. The improved strength comes from differences in cell wall composition and lower expression of a hydrophobin gene, offering new possibilities for bio-based material development.

Anisotropic Growth of Filamentous Fungi in Wood Hydrogel Composites Increases Mechanical Properties

Researchers developed new composite materials by growing fungi on specially treated wood. The fungi naturally grow along the wood’s fiber direction, creating stronger, more organized structures than they would in regular gelatin. By adjusting the wood type and nutrient levels, scientists could precisely control the mechanical strength of these eco-friendly materials, which could eventually be used in building products and packaging.

Mycofabrication of sustainable mycelium-based leather using Talaromyces sp. and irradiated eggplant peel waste

mycolabadmin

Scientists developed a new type of eco-friendly leather made from fungal mycelium grown on eggplant peel waste. Using radiation to treat the eggplant peels made them stronger and more flexible, and optimizing the growing conditions improved the material’s quality. The resulting mycoleather has mechanical properties comparable to real leather but is completely biodegradable and sustainable, offering a promising alternative to traditional leather production.

Impact of Fomes fomentarius growth on the mechanical properties of material extrusion additively manufactured PLA and PLA/Hemp biopolymers

mycolabadmin

This research explores how mushroom mycelium can be integrated with 3D-printed plastic materials to create sustainable biocomposites. Scientists tested whether Fomes fomentarius fungus growing on printed PLA and hemp-reinforced plastic specimens affected their strength and stiffness. Results showed that while pure PLA remained largely unaffected by mycelium growth, hemp-reinforced materials experienced some weakening, with effects depending on the duration of fungal colonization and the internal structure of the printed materials. These findings suggest potential applications in developing eco-friendly building materials and insulation products that combine the benefits of living organisms with manufactured polymers.

Cross-linking impacts the physical properties of mycelium leather alternatives by targeting hydroxyl groups of polysaccharides and amino groups of proteins

mycolabadmin

Scientists developed a leather-like material made from mushroom mycelium by treating it with chemical cross-linkers similar to those used in traditional leather tanning. The best results came from using glutaraldehyde, which chemically bonded to the mycelium’s proteins and carbohydrates, creating a stronger and more durable material. While the mycelium leather now has comparable strength to conventional leather, it needs to be more flexible. This research offers a more environmentally sustainable alternative to animal leather.

Strongest untreated mycelium materials produced by Schizophyllum commune dikaryons

mycolabadmin

Scientists have developed a new method to produce exceptionally strong mushroom-based materials by using dikaryotic strains of Schizophyllum commune instead of monokaryotic strains. These new materials achieved record-breaking strength of 47 MPa, making them stronger than existing mycelium materials while maintaining flexibility. The enhanced strength comes from differences in cell wall composition and lower expression of a specific gene that normally affects material density. This breakthrough could lead to improved fungal-based alternatives for leather and textiles.
