Novel chia (Salvia Hispanica L.) residue-based substrate formulations for oyster mushroom (Pleurotus ostreatus) cultivation

mycolabadmin

Researchers discovered that leftover plant material from chia seed production can be used to grow oyster mushrooms with excellent nutritional value. When chia residues were combined with rice straw in the right proportions, they produced mushrooms with higher protein content, more beneficial compounds, and better yields than traditional growing methods. This finding helps solve two problems at once: it creates a valuable use for chia farming waste while producing highly nutritious mushrooms for human consumption.

Nomilin from Yuzu Seed Has In Vitro Antioxidant Activity and Downregulates Melanogenesis in B16F10 Melanoma Cells through the PKA/CREB Signaling Pathway

mycolabadmin

Scientists extracted a compound called nomilin from yuzu seeds and tested whether it could lighten skin by reducing melanin production. They found that nomilin works by blocking an enzyme called tyrosinase that makes melanin, and it reduces the activity of cell signaling pathways involved in skin darkening. The study shows nomilin could be used as a natural skin-whitening ingredient in cosmetics without the side effects of synthetic alternatives.

Unlocking Reishi’s secrets: nutritional and medicinal traits of Ganoderma lucidum isolated from tree bark in Egypt

mycolabadmin

Reishi mushrooms (Ganoderma lucidum) from Egypt show promise as natural medicine. Researchers tested extracts and found they can fight bacteria, viruses, and cancer cells in laboratory tests. The mushrooms are rich in beneficial compounds like vitamins and antioxidants. While the extract was not as strong as conventional drugs, it showed good safety profiles and potential for development into new medicines.

Biological Characteristics and Domestication of Dichomitus squalens and the Antioxidant Activity of Its Cultivated Fruiting Bodies

mycolabadmin

Researchers cultivated a type of fungus called Dichomitus squalens and extracted beneficial compounds called polysaccharides from its fruiting bodies. These polysaccharides showed strong antioxidant properties, meaning they can help protect cells from damage caused by harmful free radicals. The study identified the best growing conditions for this fungus and developed methods for farming it, suggesting it could become a natural source of antioxidants for health applications.

FTIR Characterization and Bioactivity Assessment of Cinnamomum camphora Essential Oil: Antioxidant, Anti-Enzymatic, and Antifungal Properties Against Phytopathogens

mycolabadmin

Camphor tree essential oil has been studied for its ability to fight fungal diseases that harm crops and its potential health benefits. The research found that this natural oil completely stops the growth of several harmful fungi at high concentrations, making it a promising eco-friendly alternative to synthetic pesticides. The oil also showed antioxidant properties and may help regulate blood sugar levels, suggesting uses in both agriculture and medicine.

Artificial intelligence-assisted optimization of extraction enhances the biological activity of Phylloporia ribis

mycolabadmin

Scientists optimized how to extract beneficial compounds from Phylloporia ribis mushrooms using artificial intelligence, finding that an AI-assisted method produced extracts with stronger antioxidant power and cancer-fighting properties than traditional statistical approaches. The optimized extracts showed promise in fighting free radicals, potentially supporting brain health against Alzheimer’s disease, and slowing cancer cell growth. This research demonstrates how combining mushroom extraction with modern AI technology could lead to more effective natural medicines.

Transcriptom Analysis of Auricularia auriculla-judae Fruit Body Treated with Gamma Radiation on Mycelium

mycolabadmin

Researchers studied how the wood ear mushroom (Auricularia auricula-judae) responds to gamma radiation at the genetic level. They found that when exposed to radiation, the mushroom activates DNA repair mechanisms and eliminates damaged cells through cell death, rather than relying on antioxidant defenses like some other fungi. This research helps us understand how edible mushrooms naturally protect themselves from radiation damage.

Mycosynthesis of Metal-Containing Nanoparticles—Synthesis by Ascomycetes and Basidiomycetes and Their Application

mycolabadmin

Scientists have discovered that common fungi like mushrooms and molds can produce tiny nanoparticles that fight bacteria, kill cancer cells, and speed up chemical reactions. This fungal method is much cheaper, safer, and more environmentally friendly than traditional chemical production methods. The nanoparticles can be used in medical treatments, wound dressings, water purification, and farming as natural fertilizers and pesticides.

Evaluation of the Nutritional and Health Values of Selected Polish Mushrooms Considering Fatty Acid Profiles and Lipid Indices

mycolabadmin

This study analyzed three popular Polish mushroom species to understand their nutritional value, particularly focusing on their fatty acid content. The mushrooms were found to be rich in healthy unsaturated fats, similar to plant-based oils rather than animal fats. The research indicates these mushrooms may help reduce the risk of heart disease and could be beneficial for people with high blood pressure when included in regular diets.

Ultrasound-Assisted Preparation of Chitosan Oligosaccharide-Stabilized Thyme Oil-in-Water Nanoemulsions: Enhanced Storage Stability and Antimicrobial Properties

mycolabadmin

Researchers created tiny droplets of thyme oil mixed in water using sound waves and a natural stabilizer from shellfish shells. These droplets stayed stable for weeks without separating and worked twice as well at fighting bacteria and mold compared to regular thyme oil. The new formula could be used to keep fresh food from spoiling during storage.
