Degradation of Cellulose Derivatives in Laboratory, Man-Made, and Natural Environments

mycolabadmin

This comprehensive review examines how cellulose-based plastics break down in different environments like compost, soil, and oceans. The key finding is that how much the cellulose is chemically modified (measured by degree of substitution) dramatically affects how quickly it biodegrades. The research shows that properly designed cellulose derivatives can be sustainable alternatives to conventional plastics, especially for products like agricultural films and packaging that often end up in the environment.

Use of Limestone Sludge in the Preparation of ɩ-Carrageenan/Alginate-Based Films

mycolabadmin

Researchers have developed a method to convert limestone waste from stone quarries into a useful material for making biodegradable plastic films. By dissolving limestone in acid to extract calcium ions, they created a crosslinking solution that strengthens films made from seaweed-derived compounds like alginate and carrageenan. These films show promise as environmentally-friendly alternatives to conventional plastic packaging while helping solve industrial waste problems.

Comparative Evaluation of Mechanical and Physical Properties of Mycelium Composite Boards Made from Lentinus sajor-caju with Various Ratios of Corn Husk and Sawdust

mycolabadmin

Researchers developed biodegradable composite boards using mushroom mycelium (Lentinus sajor-caju) grown on agricultural waste like corn husks and sawdust. By adjusting the ratio of these materials and board thickness, they created boards with properties comparable to commercial softboards and acoustic panels. These eco-friendly boards could replace synthetic materials in construction and furniture, reducing waste and pollution while maintaining good mechanical strength and sound absorption properties.

Strongest untreated mycelium materials produced by Schizophyllum commune dikaryons

mycolabadmin

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.

Fungal Strain Influences Thermal Conductivity, Hydrophobicity, Color Homogeneity, and Mold Contamination of Mycelial Composites

mycolabadmin

Scientists tested mushroom-based materials grown on hemp for use as eco-friendly insulation. They compared nine different mushroom species to see which created the best insulation with desired properties. Some materials performed as well as or better than commercial foam insulation, and they discovered a novel way to prevent mold growth by exposing developing materials to dead mold spores.

A Comprehensive Review on Studying and Developing Guidelines to Standardize the Inspection of Properties and Production Methods for Mycelium-Bound Composites in Bio-Based Building Material Applications

mycolabadmin

This review examines mycelium-based composites, which are innovative building materials made from fungal networks grown on agricultural waste. These eco-friendly materials are biodegradable and use less energy to produce than traditional construction materials. The authors analyze current testing methods and propose standardized production guidelines to ensure consistent quality, helping make these sustainable materials more reliable for widespread use in buildings and construction.

Biomimicry in the Context of Stabilised Porous Clays

mycolabadmin

Researchers developed a new way to strengthen loose soil by mimicking how fungi naturally stabilize soil in nature. Instead of compacting soil (which reduces its ability to support plant growth and fluid movement), they treat it with a waste product from sugar refineries mixed with a binding agent. The treated soil becomes stronger and stiffer while remaining porous and loose, maintaining its ability to support ecosystem functions while meeting engineering requirements.
