Use of Ganoderma lucidum grown on agricultural waste to remove antibiotics from water

mycolabadmin

Researchers discovered that a type of mushroom called Ganoderma lucidum can help clean water contaminated with antibiotics. When the mushroom is grown on leftover agricultural materials like almond shells and coffee grounds, its root-like structure can remove certain antibiotics from water in just three days. This offers a cheap and sustainable way to address antibiotic pollution that contributes to antibiotic-resistant infections.

The Lignicolous Fungus Hericium erinaceus (Lion’s Mane Mushroom): A Promising Natural Source of Antiradical and DPPH Inhibitory Agents

mycolabadmin

Lion’s Mane mushrooms grown on a special mixture of agricultural waste materials showed the best antioxidant properties in this study. Researchers found that combining sawdust, wheat straw, bagasse, rice bran, and corn flour created the ideal growing environment. The mushrooms produced high levels of protective compounds called phenolics and flavonoids that help fight harmful free radicals in the body. This research shows how we can turn agricultural waste into valuable medicinal mushrooms with strong health benefits.

Enzymatic Activity and Nutrient Profile Assessment of Three Pleurotus Species Under Pasteurized Cenchrus fungigraminus Cultivation

This study tested growing oyster mushrooms on a special grass called Cenchrus fungigraminus that was heat-treated to remove harmful organisms. Three types of oyster mushrooms were grown, and researchers measured the enzymes they produced and the nutrition in the harvested mushrooms. The oyster mushroom species Pleurotus ostreatus grew fastest and produced the best yields, and the grass substrate proved to be an effective and affordable choice for small-scale mushroom farming.

Impact of Artemisia argyi and Stevia rebaudiana substrate composition on the nutritional quality, yield and mycelial growth of L. edodes addressing future food challenges

mycolabadmin

This study tested using wormwood and stevia plant waste as alternatives to traditional wood chips in shiitake mushroom farming. Results showed that adding up to 45% wormwood or 30% stevia to growing substrates increased both the amount and nutritional quality of mushrooms produced. This sustainable approach addresses mushroom farming’s resource shortage while potentially improving the nutritional value of the final product, making it beneficial for both food production and environmental protection.

Solid-state fermentation of hemp waste: enhancing the performance of Hermetia illucens larvae and altering the composition of hemp secondary metabolites

mycolabadmin

Researchers tested whether fermenting hemp plant waste with different mushroom types could make it a better food source for black soldier fly larvae, which produce valuable protein for animal feed. They found that different mushroom species had different effects: Ganoderma lucidum significantly increased the amount of larvae produced, while Trichoderma reesei increased beneficial cannabinoid content. Pleurotus ostreatus and Hypsizygus ulmarius removed unwanted cannabinoids from the waste. This approach offers a promising way to turn hemp waste into high-quality insect feed while controlling the levels of bioactive compounds.

Fermentation of cocoa pod husks with Pleurotus salmoneo-stramineus for food applications

mycolabadmin

Researchers found a way to transform cocoa pod husks, a major waste product from cocoa production, into a nutritious food ingredient by fermenting them with a special mushroom fungus. The fermented product had nearly triple the protein content of the original husks and maintained high fiber levels, making it comparable to meat in protein quality. This innovation could help cocoa farmers create additional income while reducing waste and supporting more sustainable cocoa production.

Mycelium-Doped Straw Biochars for Antibiotic Control

mycolabadmin

Researchers developed a new type of biochar by incorporating fungal mycelium into corn straw to create highly effective water purification material. This mycelium-enhanced biochar can remove antibiotics from water more effectively than conventional biochar and maintains its performance even after being reused multiple times. The approach transforms agricultural waste into a valuable environmental solution while offering a practical, low-cost method for water treatment applications.

The Fungus Among Us: Innovations and Applications of Mycelium-Based Composites

mycolabadmin

Mycelium-based composites are eco-friendly building materials made by growing mushroom fungus on agricultural waste like sawdust and straw. These materials are lightweight, provide excellent insulation and soundproofing, and are much more sustainable than synthetic alternatives. However, they absorb water easily and aren’t strong enough for load-bearing structures, making them best suited for insulation and non-structural panels.
