Synthesis of Acetobacter xylinum Bacterial Cellulose Aerogels and Their Effect on the Selected Properties

mycolabadmin

Scientists created a special lightweight foam-like material made from bacterial cellulose that could be used in wound dressings, insulation, and water filtration. The material was made sustainably using just tea, sugar, and bacteria—no harmful chemicals needed. Different freezing methods were tested to create the best possible structure, with liquid nitrogen freezing producing the most porous and uniform results. The material showed excellent insulation properties and is biodegradable, making it an environmentally friendly alternative to synthetic foams.

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.

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

mycolabadmin

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.

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.
