Olive mill solid waste induces beneficial mushroom-specialized metabolite diversity revealed by computational metabolomics strategies

mycolabadmin

This study shows how adding olive mill waste to mushroom growing substrate can increase beneficial compounds in mushrooms while reducing harmful toxins. Researchers grew two types of edible mushrooms (lion’s mane and king oyster) on substrate containing different amounts of olive mill waste and used advanced chemical analysis to identify how the waste affected the mushrooms’ medicinal compounds. Adding olive mill waste increased healthy compounds like hericenones and erinacerins while decreasing toxic enniatin compounds, potentially creating safer and more nutritious mushrooms for consumers.

Structural Elucidation of Heteropolysaccharides from the Peach-Shaped Dictyophora indusiata and Its Anti-Inflammatory Activity

mycolabadmin

Researchers extracted polysaccharides from peach-shaped bamboo fungus (Dictyophora indusiata) and discovered they contain beneficial beta-glucans. When tested on human immune cells triggered to become inflamed, these polysaccharides reduced inflammatory markers and messenger proteins. The compounds were found to be chemically stable under various conditions, suggesting potential use as a natural anti-inflammatory supplement or food ingredient.

Novel Antimicrobial Activities of Albofungin, Albonoursin, and Ribonucleosides Produced by Streptomyces sp. Caat 5-35 Against Phytopathogens and Their Potential as a Biocontrol Agent

mycolabadmin

Scientists discovered that a soil bacterium called Streptomyces sp. Caat 5-35 produces natural compounds that can kill crop-damaging pathogens. These compounds, including albofungin and albonoursin, showed strong activity against diseases affecting cacao and palm crops. The bacterium also helps plants by breaking down cellulose and making phosphorus more available, making it a promising tool for natural crop protection without synthetic chemicals.

One-Health Approach to Managing Aflatoxin-Producing Aspergillus flavus Using Spent Mushroom Substrate of Pleurotus spp

mycolabadmin

This study shows that leftover substrate from growing oyster and red mushrooms can work together with a common antifungal fungicide to better prevent harmful Aspergillus fungi from contaminating corn. The combination of mushroom waste and fungicide was more effective than using either alone, and could potentially reduce the amount of chemicals needed in agriculture while protecting the environment and preventing drug resistance.

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.

Neutral Polysaccharides From Hohenbuehelia serotina With Hypoglycemic Effects in a Type 2 Diabetic Mouse Model

mycolabadmin

Researchers extracted and studied special compounds called polysaccharides from H. serotina mushrooms. They found that these compounds significantly reduced blood sugar levels in mice with type 2 diabetes and also protected the liver. The study shows that mushroom polysaccharides could be a safe, natural alternative to existing diabetes medications with fewer side effects.

Hericioic Acids A–G and Hericiofuranoic Acid; Neurotrophic Agents from Cultures of the European Mushroom Hericium flagellum

mycolabadmin

Researchers isolated eight new bioactive compounds from a rare European mushroom species called Hericium flagellum. These compounds showed promising ability to stimulate nerve cell growth and could potentially help treat neurodegenerative diseases like Alzheimer’s and Parkinson’s. The study demonstrates that mushroom-derived natural products may offer new therapeutic approaches for conditions affecting millions of elderly people worldwide.

Isolation, purification, and structural elucidation of Stropharia rugosoannulata polysaccharides with hypolipidemic effect

mycolabadmin

Scientists extracted and studied a polysaccharide from wine cap mushrooms that shows promise for lowering cholesterol and protecting the liver. The compound, called SRF-3, has a complex sugar structure and works by binding to cholesterol and bile acids, helping the body eliminate them. Testing in laboratory conditions showed it has strong antioxidant properties and can reduce fat accumulation in liver cells, suggesting potential use as a natural supplement for managing high cholesterol.

Aspergillus terreus IFM 65899-THP-1 cells interaction triggers production of the natural product butyrolactone Ia, an immune suppressive compound

mycolabadmin

Scientists discovered that when a dangerous fungus called Aspergillus terreus is grown together with immune cells, it produces a special compound called butyrolactone Ia that helps it hide from the body’s defense system. This compound works by reducing inflammatory signals that immune cells use to fight the fungus. The research shows that direct contact between the fungus and immune cells is needed to trigger this protective compound production, suggesting the fungus responds directly to the threat of immune attack.

Antifungal effects of metabolites from Arthrinium sp. 2–65 and identification of main active ingredients

mycolabadmin

Scientists discovered that a fungus called Arthrinium sp. 2–65, found living inside a wild plant called Thymus mongolicus, produces two special compounds that can kill the fungus responsible for grey mould disease. Grey mould is a major problem for farmers worldwide, damaging crops like tomatoes, grapes, and strawberries. These newly identified compounds were tested and showed excellent effectiveness against the disease, offering a promising natural alternative to chemical pesticides that have become less effective due to resistance and environmental concerns.
