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.

Bioactivity and toxicity of polysaccharides derived from the phytopathogenic mushroom Ganoderma orbiforme cultured in a bioreactor

mycolabadmin

Scientists studied a mushroom called Ganoderma orbiforme that normally harms oil palm trees to see if it could be useful as medicine. They grew the mushroom in a special bioreactor and extracted beneficial substances called polysaccharides. These substances showed promise as natural antibiotics and antioxidants while being safe for use based on safety testing with fish embryos.

Endophytic fungi isolated from Vietnamese nut grass (Cyperus rotundus L. Cyperaceae) – A promising solution to mitigate the prime phenomenon of antibiotic resistance

mycolabadmin

Scientists discovered seven types of fungi living inside nut grass plants that can fight dangerous bacteria, including those resistant to current antibiotics. These fungi showed strong ability to kill drug-resistant staph bacteria and other serious pathogens. The findings suggest that these naturally-occurring fungi could be developed into new antibiotics to treat infections that currently have limited treatment options.

Descriptions of 19 Unrecorded Species Belonging to Sordariomycetes in Korea

Scientists in Korea discovered and documented 19 species of fungi that were previously unrecorded in the country. These fungi were found in soil and freshwater environments across Korea. Using microscopy and DNA analysis, the researchers confirmed the identity of each species and provided detailed descriptions and illustrations. This discovery helps us better understand the fungal diversity present in Korean ecosystems.

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

This study shows that shiitake mushrooms can be grown on agricultural waste materials like wormwood and stevia instead of traditional sawdust. Using 45% wormwood or 30% stevia in the growing substrate improved both the mushroom yield and their nutritional content, including important compounds with health benefits. These findings suggest environmentally friendly and sustainable alternatives for mushroom farming that reduce reliance on wood resources while maintaining or improving food quality.

Antifungal and other bioactive properties of the volatilome of Streptomyces scabiei

mycolabadmin

Researchers discovered that Streptomyces scabiei, a bacterium known for causing common scab disease on potatoes and other root vegetables, produces various airborne chemicals with surprising benefits. Using advanced laboratory techniques, scientists identified 36 different volatile compounds from this bacterium, many of which can kill harmful fungi and potentially help plants grow better. While traditionally viewed as purely harmful, these findings suggest the bacterium may actually serve a more complex role in soil, sometimes protecting crops from more dangerous diseases.

Isolation and identification of endophytic fungi from Alhagi sparsifolia Shap. and their antibacterial activity

mycolabadmin

Researchers discovered ten types of fungi living inside the medicinal plant Alhagi sparsifolia that were never found before. Two of these fungi produced substances that killed harmful bacteria better than standard antibiotics, especially against E. coli. The researchers identified 26 different compounds in these fungi that are responsible for their antibacterial effects. This research opens new possibilities for developing natural antibacterial medicines from fungal sources.

Biosynthesis of bimetallic silver–copper oxide nanoparticles using endophytic Clonostachys rosea ZMS36 and their biomedical applications

mycolabadmin

Scientists discovered a special fungus living inside a medicinal plant that can create tiny silver-copper nanoparticles with powerful antibacterial and anti-cancer properties. These nanoparticles successfully fought dangerous bacteria like MRSA and slowed the growth of cancer cells while being safe to healthy cells. This green manufacturing method is much more environmentally friendly than traditional chemical approaches and could lead to new treatments for infections and cancer.

Enhancing the Yield of Pleurotus ostreatus Through the Addition of Nucleotides and Nucleosides

mycolabadmin

Researchers discovered that adding nucleotides and nucleosides to oyster mushroom growing medium significantly increases mushroom yield and nutritional value. These compounds enhanced the dietary fiber and amino acid content while helping the mushrooms break down tough plant materials more efficiently. The study suggests that nucleosides are particularly effective and could provide a simpler, safer alternative to traditional mushroom cultivation methods that involve lengthy composting processes.

Extraction and Identification of the Bioactive Metabolites Produced by Curvularia inaequalis, an Endophytic Fungus Collected in Iran from Echium khuzistanicum Mozaff

mycolabadmin

Researchers discovered a fungus living inside an Iranian medicinal plant that produces three natural compounds with powerful antimicrobial properties. The most promising compound, phomalactone, killed dangerous bacteria including MRSA and also prevented growth of fungal plant diseases. This discovery shows that exploring symbiotic fungi in medicinal plants could lead to new natural antibiotics and agricultural fungicides.
