Pleurotus eryngii Culture Filtrate and Aqueous Extracts Alleviate Aflatoxin B1 Synthesis

mycolabadmin

This research demonstrates that extracts from oyster mushrooms (Pleurotus eryngii) can effectively prevent the production of aflatoxin B1, a highly toxic and cancer-causing substance produced by certain molds that contaminate crops like corn and wheat. The mushroom extracts work by inhibiting the toxin production by up to 94%, offering a natural, environmentally-friendly alternative to chemical pesticides. The study suggests that compounds in mushrooms, including special sugars and enzymes, may help protect food supplies from this dangerous contamination, which is becoming increasingly important as climate change creates more favorable conditions for mold growth.

Green synthesis of silver nanoparticles using fermentation extracts from a mangrove soil bacterium: morphological characterization, and antifungal activities against rice blast fungus

mycolabadmin

Researchers developed tiny silver particles made from bacteria found in mangrove soil that effectively kill the fungus causing rice blast disease. These nanoparticles work better than current chemical fungicides and are much safer for the environment and aquatic life. The particles stop the fungus from growing and spreading in rice plants, offering farmers a sustainable alternative to traditional chemical pesticides.

Biocontrol of Cheese Spoilage Moulds Using Native Yeasts

mycolabadmin

This research explores using naturally occurring yeasts found in cheese to prevent mould spoilage, offering a chemical-free alternative to current preservatives. Scientists tested 84 yeast strains and identified the most promising ones that can inhibit growth of three common spoilage moulds through different mechanisms like enzyme production and nutrient competition. Two yeast strains, Geotrichum candidum GC663 and Pichia jadinii PJ433, showed particularly strong potential for protecting cheese quality and extending shelf life when tested in actual cheese.

Synthesis of silver nanoparticles employing Polyalthia longifolia leaf extract and their in vitro antifungal activity against phytopathogen

mycolabadmin

Scientists successfully created tiny silver particles using leaves from the Polyalthia longifolia plant, an evergreen tree native to India. These silver nanoparticles proved highly effective at stopping the growth of Alternaria alternata, a fungus that damages crops and causes leaf spot disease. The method is inexpensive, environmentally friendly, and the particles remain stable for months, making them a promising natural alternative to chemical fungicides for protecting plants.

Characterization of Two Potential Biocontrol Bacillus Strains Against Maize Stalk Rot

mycolabadmin

Scientists discovered two beneficial bacteria, Bacillus subtilis and Bacillus siamensis, that can protect maize plants from a serious fungal disease called stalk rot. These bacteria work in two ways: they directly kill the fungus and they promote healthy plant growth. By analyzing the bacteria’s genetic makeup, researchers found that they produce multiple natural antibiotic compounds that explain their powerful disease-fighting abilities. This research suggests these bacteria could be used as a natural, environmentally-friendly alternative to chemical fungicides for protecting crops.

Synergistic inhibition of Aspergillus flavus by organic acid salts: growth, oxidative stress, and aflatoxin gene modulation

mycolabadmin

A dangerous fungus called Aspergillus flavus contaminates animal feed and produces harmful toxins called aflatoxins that can make animals sick. Researchers tested a combination of three salt-based organic acids commonly used as natural food preservatives and found they work together to kill this fungus much better than using them individually. The combination damages the fungus’s cell structure, creates harmful reactive oxygen inside the cells, and shuts down the genes that produce the toxins, making it an excellent safe option for protecting animal feed.

Control effects and mechanisms of metabolites from Streptomyces ahygroscopicus var. gongzhulingensis strain 769 on sclerotinia rot in sunflowers

mycolabadmin

Scientists discovered that a beneficial soil bacterium called Streptomyces can effectively control sunflower rot disease caused by a harmful fungus. When applied to soil or roots, this bacterium reduced disease severity by over 50% and improved plant root health and seed quality. The treatment works by both directly killing the pathogenic fungus and strengthening the plant’s natural defense systems.

An implementation framework for evaluating the biocidal potential of essential oils in controlling Fusarium wilt in spinach: from in vitro to in planta

mycolabadmin

Researchers tested four common essential oils (thyme, oregano, marjoram, and tea tree) to see if they could stop a dangerous fungal disease in spinach plants. They found that thyme and oregano oils worked best at killing the fungus in laboratory tests and when applied to spinach seeds in the greenhouse, with thyme oil reducing disease by over half without harming the plants.

A novel partitivirus confers dual contradictory effects to its host fungus: growth attenuation and virulence enhancement

mycolabadmin

Researchers discovered a new virus that infects a fungus causing disease in tea plants. Interestingly, this virus has opposing effects: it slows down the fungus’s growth but makes it more damaging to tea leaves. This unusual combination of effects provides new insights into how viruses interact with fungal pathogens and could inform new strategies for managing tea plant diseases.

Antifungal mechanism of ketone volatile organic compounds against Pseudogymnoascus destructans

mycolabadmin

Researchers discovered that two ketone compounds, 2-undecanone and 2-nonanone, effectively kill Pseudogymnoascus destructans, the fungus that causes white-nose syndrome in bats. Using advanced genetic analysis, they found these ketones work by damaging the fungus’s cell structure, disrupting its energy production, and causing DNA damage. This research provides a foundation for developing new fumigant treatments to protect bat populations from this devastating fungal disease.
