Antifungal and other bioactive properties of the volatilome of Streptomyces scabiei

mycolabadmin

This research discovered that the bacterium Streptomyces scabiei, which causes common scab disease on potatoes and other root crops, produces a variety of natural chemical compounds that can kill harmful fungi and promote plant growth. Scientists identified 36 different volatile chemicals released by this bacterium, including some previously unknown for their antifungal abilities. These findings suggest that despite being a plant pathogen, this bacterium may actually help protect crops from more dangerous diseases, offering potential for developing natural alternatives to synthetic pesticides.

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.

Bioactive Properties of Selected European Phellinus Species: A Comprehensive Study

mycolabadmin

This research examined 30 samples of medicinal mushrooms from the Phellinus genus collected across Europe, including Poland, Italy, Portugal, Kosovo, and North Macedonia. Scientists found that three species—Phellinus igniarius, Fomitiporia robusta, and Porodaedalea pini—are particularly rich in beneficial compounds, especially polysaccharides and antioxidants. These mushroom extracts showed impressive abilities to fight antibiotic-resistant bacteria and protect cells from oxidative damage, suggesting they could become valuable sources for new medicines and functional foods.

Ascosphaera apis as a target for the antifungal activity of symbiotic Bifidobacteria in honey bees

mycolabadmin

Researchers found that certain beneficial bacteria (Bifidobacterium asteroides) living in honey bee guts can fight the fungus that causes chalkbrood disease, a serious condition affecting bee colonies. These bacteria produce natural compounds, especially propanoic acid and ethanol, that kill the fungus and prevent it from growing. This discovery offers a safe, natural alternative to chemical treatments for protecting honeybees from fungal infections while maintaining colony health.

Effects of Drying Methods on Taste Components and Flavor Characterization of Cordyceps militaris

mycolabadmin

This research compared four different ways to dry Cordyceps militaris mushrooms to determine which method best preserves their delicious taste and aroma. The study found that microwave combined with hot air drying created the strongest umami or savory taste, while vacuum freeze drying best preserved the mushroom’s natural aroma and flavor compounds. These findings help food manufacturers choose the best drying method to maintain the quality and desirable characteristics of Cordyceps militaris products for consumers.

Bacillus velezensis LMY3-5 for the biocontrol of soft rot in kiwifruit: antifungal action and underlying mechanisms

mycolabadmin

Scientists discovered a beneficial bacteria called Bacillus velezensis that can effectively prevent soft rot disease in kiwifruit, which causes serious damage during storage. The bacteria works by producing natural antimicrobial compounds that damage the fungal pathogen’s cell walls and membranes, stopping it from growing. This biocontrol approach offers an environmentally friendly alternative to chemical fungicides, reducing pesticide residues while maintaining fruit quality and safety.

Mechanistic insights into volatile odor changes in surimi gels with typical cross-linking degrees during frozen storage based on lipidomics analysis

mycolabadmin

When surimi (a fish-based food product) is frozen for long periods, its pleasant fish aroma fades while unpleasant fishy and oily smells develop. This study found that this change happens because fats in the surimi oxidize and break down during freezing. Using faster freezing methods and chemically strengthening the surimi’s structure can help preserve the original flavor. The research identified specific fats that are responsible for creating unwanted odors, providing guidance for better preservation techniques.

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.

Biocontrol Potential of a Mango-Derived Weissella paramesenteroides and Its Application in Managing Strawberry Postharvest Disease

mycolabadmin

Researchers discovered that a beneficial bacteria called Weissella paramesenteroides, naturally found on mango surfaces, can protect strawberries from fungal spoilage. This bacteria works by releasing special aromatic compounds (VOCs) into the air that kill disease-causing fungi without direct contact. When used in strawberry storage boxes, this biocontrol method reduced fruit disease from 70% to 35%, offering a safer, natural alternative to synthetic fungicides.

Anti-Melanogenic Activity of Calocedrus formosana Wood Essential Oil and Its Chemical Composition Analysis

mycolabadmin

Researchers tested an essential oil from Taiwan’s precious Calocedrus formosana wood to see if it could lighten skin by blocking melanin production. The oil worked very well at stopping melanin synthesis in laboratory cells, with a compound called thymol being responsible for most of the lightening effect. This natural product could potentially be used in skin whitening cosmetics and offers a safer alternative to synthetic ingredients.
