Enhancing the Substrate Adaptability of Laccase through Ancestral Sequence Reconstruction for Applications in Mycotoxin Detoxification

mycolabadmin

Researchers used evolutionary analysis to redesign a fungal enzyme called laccase to better detoxify harmful mold toxins found in grains. The new engineered enzyme (LacANC278) can break down both aflatoxin and zearalenone toxins much more effectively than the original enzyme, and converts them into less harmful substances. This enzyme works without expensive helper chemicals and works well at room temperature, making it practical for treating contaminated corn and other grains.

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.

Lactic acid bacteria: beyond fermentation to bio-protection against fungal spoilage and mycotoxins in food systems

mycolabadmin

Mold and fungal toxins spoil food and threaten human health, costing billions globally. While chemical preservatives work, many consumers want natural alternatives. Lactic acid bacteria (the same organisms used in yogurt production) produce natural antimicrobial compounds that can prevent mold growth and neutralize harmful toxins, offering a safer, more natural way to keep food fresh longer.

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.

The Efficacy of Clove Oil Against Aspergillus flavus and the Production of Aflatoxin B1 in Organic Peanuts in Georgia

mycolabadmin

Researchers tested clove essential oil as a natural antifungal treatment for peanuts infected with a mold that produces aflatoxin, a dangerous toxin harmful to human health. They found that clove oil significantly reduced both the mold growth and toxin production, with the best results at moderate concentrations. This discovery offers organic farmers an eco-friendly alternative to synthetic fungicides for protecting their peanut crops. The findings could help reduce a major agricultural problem that costs the Southeast millions of dollars annually.

Functional Characterization of FgAsp, a Gene Coding an Aspartic Acid Protease in Fusarium graminearum

mycolabadmin

Scientists studied a specific gene called FgAsp in a fungus that causes wheat disease and produces harmful toxins. By deleting this gene, they found it controls important fungal processes like growth, reproduction, and the ability to infect wheat plants. The modified fungus produced less toxin and was less harmful, suggesting this gene could be targeted to develop new fungicides to protect crops.

Inhibitive effect of Urginea epigea methanolic extract and silver/zinc oxide nanoparticles on Aspergillus and aflatoxin production

mycolabadmin

Researchers tested whether a plant called Urginea epigea could stop the growth of a dangerous fungus (Aspergillus flavus) that produces aflatoxins, which can harm humans and animals. The plant extract completely stopped fungus growth at high concentrations and significantly reduced the production of toxins by turning off the genes responsible for toxin production. This suggests that plant-based treatments could offer a natural alternative to synthetic chemical fungicides for protecting food from contamination.

Transcriptome analysis of Ochratoxin A (OTA) producing Aspergillus westerdijkiae fc-1 under varying osmotic pressure

mycolabadmin

This research studied how salt concentration affects the production of ochratoxin A, a toxic substance produced by the fungus Aspergillus westerdijkiae that contaminates foods like coffee and grapes. Using advanced genetic analysis, scientists found that moderate salt levels (20 g/L) increase the fungus’s ability to produce this toxin by affecting specific genes. The findings help explain why OTA contamination is more common in salty foods like cured meats and suggest new ways to prevent this contamination and protect food safety.

Modelling the Combined Effects of Oxalic Acid, Water Activity, and pH on the Growth and Mycotoxin Production of Aspergillus spp. in a Dried Fig System

mycolabadmin

Dried figs can become contaminated with harmful fungi that produce dangerous toxins during the drying process. Researchers used mathematical modeling to understand how water content, acidity, and oxalic acid treatment affect fungal growth and toxin production in figs. They found that reducing water content is the most effective way to prevent dangerous toxin buildup. These models help the fig industry identify and avoid conditions that promote contamination, ultimately making dried figs safer for consumers.

Removal of Aflatoxin B1 by Edible Mushroom-Forming Fungi and Its Mechanism

mycolabadmin

This research discovered that edible mushroom varieties, particularly Bjerkandera adusta, can remove harmful aflatoxin B1 poison from food and animal feed. The mushroom fungi work by binding the toxin to their cell structures, acting like a sponge that soaks up the dangerous chemical. This natural method is safer and more practical than chemical or heat-based approaches because it doesn’t damage the nutritional value of food while making it safer to eat.
