Sustainable Extraction and Multimodal Characterization of Fungal Chitosan from Agaricus bisporus

mycolabadmin

Researchers successfully extracted chitosan from button mushrooms (Agaricus bisporus) using environmentally friendly chemical processes. This fungal-derived chitosan offers a sustainable alternative to traditional sources from shellfish and avoids issues like allergies and harsh chemical pollution. The extracted material showed promising properties for medical applications including wound healing and drug delivery systems.

Esterase and Peroxidase Are Involved in the Transformation of Chitosan Films by the Fungus Fusarium oxysporum Schltdl. IBPPM 543

mycolabadmin

Scientists discovered that a common fungus called Fusarium oxysporum can modify chitosan films (made from a natural polymer related to shellfish shells) without destroying them. The fungus produces special enzymes that change the structure of the films, making them stronger and less soluble in acidic solutions. These modified films could be useful for creating new medical devices, drug carriers, and other materials.

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

mycolabadmin

Scientists discovered a beneficial fungus living inside the leaves of an Iranian medicinal plant. They isolated three compounds from this fungus, with the main compound showing powerful activity against drug-resistant bacteria and plant-damaging fungi. This discovery suggests that beneficial fungi within plants could be valuable sources for developing new medicines and natural pesticides.

Plant-Based Meat Analogues: Exploring Proteins, Fibers and Polyphenolic Compounds as Functional Ingredients for Future Food Solutions

mycolabadmin

This review explores how plant-based ingredients can be used to create meat-like products that are healthier and more sustainable. By combining plant proteins, fibers, and natural compounds from fruits and vegetables, scientists are developing meat alternatives that taste and feel like real meat while offering nutritional and environmental benefits. The paper discusses which plants work best, how to extract and use these ingredients, and what challenges still need to be overcome to make these products widely available and affordable.

Research advances in fungal polysaccharides: production, extraction, characterization, properties, and their multifaceted applications

mycolabadmin

This comprehensive review examines fungal polysaccharides, which are complex sugar molecules found in mushrooms and fungi that have powerful health benefits. Researchers describe how to grow and extract these compounds from various fungi, and explain their uses in treating diseases like cancer, reducing inflammation, and boosting immunity. The review covers different growing and extraction methods used worldwide and discusses future directions for using these natural compounds in medicine and industry.

Inhibition Mechanism of Cinnamomum burmannii Leaf Essential Oil Against Aspergillus flavus and Aflatoxins

mycolabadmin

This research shows that essential oil from cinnamon leaves can effectively prevent a dangerous fungus (Aspergillus flavus) from contaminating stored foods like peanuts and grains, and stops it from producing a cancer-causing toxin called aflatoxin. The oil works by damaging the fungus’s cell membrane, disrupting its energy production, and triggering stress responses. Ten main aromatic compounds in the oil, especially eucalyptol and borneol, are responsible for this protective effect. This suggests cinnamon leaf oil could be used as a natural, safe alternative to chemical fungicides for protecting stored food.

A characteristic rash caused by Shiitake mushrooms – An emerging concern?

mycolabadmin

Eating raw or undercooked Shiitake mushrooms can cause a distinctive whip-like rash in some people called Shiitake mushroom dermatitis. This dramatic rash appears 2-5 days after consumption but is not dangerous and goes away on its own in 10-14 days. The condition is caused by a compound called Lentinan that breaks down when mushrooms are cooked at higher temperatures, so properly cooking Shiitake mushrooms prevents the reaction.

Chemical profile and bioactivity of essential oils from five Turkish thyme species against white mold fungal disease agent Sclerotinia sclerotiorum

mycolabadmin

Researchers studied five types of Turkish thyme plants to see if their essential oils could fight a harmful fungus called Sclerotinia sclerotiorum that damages crops like cucumbers and sunflowers. They found that thyme oils, especially those rich in carvacrol and thymol, were very effective at stopping fungal growth. These natural plant oils could be used as safer alternatives to chemical fungicides in farming, reducing environmental damage while controlling plant diseases.

Impact of Various Essential Oils on the Development of Pathogens of the Fusarium Genus and on Health and Germination Parameters of Winter Wheat and Maize

mycolabadmin

Researchers tested four plant-based essential oils as natural alternatives to chemical fungicides for protecting wheat and maize seeds from harmful Fusarium fungi. Thyme oil proved most effective at preventing fungal infections and seedling disease, performing as well as synthetic fungicides. However, thyme oil at higher doses harmed seed germination and plant growth, suggesting careful dose selection is needed for practical use. The findings indicate essential oils could replace chemical pesticides while maintaining crop safety, though different oils must be tested for various crops.

Identification, characterization, antimicrobial activity and biocontrol potential of four endophytic fungi isolated from Amazonian plants

mycolabadmin

Scientists isolated four types of fungi living inside the leaves of medicinal plants from the Amazon region of Bolivia. These fungi produce natural compounds that kill harmful bacteria and fungi that damage potato crops. The findings show promise for developing natural alternatives to synthetic pesticides and antibiotics for agricultural and medical applications.
