You Are What You Eat: How Fungal Adaptation Can Be Leveraged toward Myco-Material Properties

mycolabadmin

Fungi can be grown to create eco-friendly materials that could replace plastics and petroleum-based products. By controlling what fungi eat and where they grow, scientists can engineer the properties of these materials to be stronger, more flexible, or water-resistant. This approach leverages the natural ability of fungi to break down organic matter and adapt to their environment. Companies like IKEA and Dell are already using these fungal materials in product packaging.

Alternative oxidase gene induced by nitric oxide is involved in the regulation of ROS and enhances the resistance of Pleurotus ostreatus to heat stress

mycolabadmin

Oyster mushrooms are commonly grown in controlled facilities but struggle with high summer temperatures. This study found that a molecule called nitric oxide helps mushroom cells survive heat stress by activating a special protein called alternative oxidase (AOX), which reduces harmful molecules called reactive oxygen species. By understanding this mechanism, growers may be able to improve mushroom cultivation and yield during hot weather.

Inhibitory Effects of Origanum vulgare Essential Oil on Mycogone perniciosa Growth in Agaricus bisporus Cultivation

mycolabadmin

A new study shows that oregano essential oil can effectively prevent and treat wet bubble disease in button mushrooms, a fungal infection that costs farmers millions in crop losses. The oil works better than conventional chemical fungicides and contains powerful antifungal compounds like carvacrol and thymol. When applied at the right time, oregano oil completely stopped the disease from developing while maintaining healthy mushroom yields. This natural solution could help organic mushroom farmers reduce their reliance on synthetic chemicals.

Toxicity of Volatile Organic Compounds Produced by Pathogens Ewingella americana and Cedecea neteri Associated with Pleurotus pulmonarius

mycolabadmin

Researchers discovered that two types of bacteria (Ewingella americana and Cedecea neteri) causing diseases in oyster mushrooms (Pleurotus pulmonarius) produce harmful volatile compounds. These airborne toxins, especially one called 2,4-di-tert-butylphenol, can damage mushroom tissue and stop mushroom growth at very low concentrations. This is the first study showing that these bacterial volatiles are important factors in mushroom disease, which could help farmers develop better ways to detect and prevent these infections.

Sustainable Recycling of Mushroom Residue as an Effective Substitute for Cotton Hull Waste in Volvariella volvacea Cultivation: Evidence from Physicochemical and Microbiome Analyses

mycolabadmin

This research shows that mushroom waste left over from growing one type of mushroom can be recycled to grow another type of mushroom, called straw mushroom. The recycled mushroom waste works just as well as the traditional cotton hull material currently used, but costs much less money. By analyzing the bacteria and chemical changes during the composting process, scientists found that beneficial bacteria break down the organic matter effectively, making this recycling method both environmentally friendly and economically practical.

A New Exopolysaccharide from a Wood-Decaying Fungus Spongipellis borealis for a Wide Range of Biotechnological Applications

mycolabadmin

Researchers isolated and studied a new polysaccharide from the wood-decaying mushroom Spongipellis borealis. This polysaccharide is composed mainly of glucose, galactose, and mannose sugars and acts as a natural stabilizer for important enzymes used in biotechnology. When this polysaccharide is added to enzyme preparations, it significantly improves their stability and performance under various conditions, making it promising for industrial and medical applications.

Construction of a genetic linkage map and detection of quantitative trait locus for the ergothioneine content in tamogitake mushroom (Pleurotus cornucopiae var. citrinopileatus)

mycolabadmin

Researchers created the first genetic map of tamogitake mushrooms to identify genes controlling ergothioneine content. Ergothioneine is an antioxidant compound that provides health benefits like fighting inflammation and protecting brain health. They found one key genetic marker that reliably predicts which mushrooms will have high ergothioneine levels, enabling farmers to selectively breed mushrooms with enhanced health benefits.

Fungal and Microalgal Chitin: Structural Differences, Functional Properties, and Biomedical Applications

mycolabadmin

Chitin is a natural fiber found in mushroom cell walls and algae that can be extracted and used for medical applications like wound healing and drug delivery. Traditional chitin from shellfish shells contains heavy metals and requires harsh chemicals to extract, but chitin from mushrooms and algae is cleaner, more sustainable, and can be grown year-round. Scientists have developed environmentally friendly extraction methods using special solvents and enzymes that preserve the chitin’s useful properties. This makes fungal and algal chitin promising alternatives for creating biomedical materials and packaging.

Chromosome-Wide Characterization of Intragenic Crossover in Shiitake Mushroom, Lentinula edodes

mycolabadmin

This study examines how genetic material is shuffled during reproduction in shiitake mushrooms. Scientists identified 65 regions in the mushroom genome where genetic crossovers happen more frequently. They discovered that special DNA sequences and specific genes regulate where these crossovers occur. Understanding these patterns can help improve mushroom breeding programs by making it easier to combine desirable traits.

Enhancing Nutritional Quality and Functionality of Legumes: Application of Solid-State Fermentation With Pleurotus ostreatus

mycolabadmin

Researchers used a mushroom fungus (Pleurotus ostreatus) to ferment lentils, chickpeas, and soybeans, making them more nutritious and easier for the body to digest. The fermentation process reduced harmful compounds called antinutrients while boosting protein content and antioxidant power. This simple bioprocessing method could help create healthier plant-based foods that rival animal protein sources in nutritional quality.
