Key sugar transporters drive development and pathogenicity in Aspergillus flavus

mycolabadmin

Researchers studied how Aspergillus flavus fungus transports sugars, which is crucial for its growth, producing the toxic aflatoxin that contaminates crops like corn and peanuts. By removing genes responsible for sugar transport, they found that the fungus became weak, couldn’t infect plants or animals effectively, and stopped producing the dangerous aflatoxin. This discovery could help develop new strategies to prevent aflatoxin contamination in food and reduce serious fungal infections in humans.

The Effect of Aspergillus flavus on Seedling Development in Maize

mycolabadmin

Aspergillus flavus is a dangerous fungus that contaminates maize crops and produces toxic aflatoxins harmful to human and animal health. Researchers tested maize varieties to identify which are naturally resistant to this fungus using a simple laboratory method. They found significant differences in resistance among maize varieties and proposed a new evaluation system to help identify resistant varieties before they are sold to farmers, which could help reduce aflatoxin contamination in our food supply.

Implantation of Aspergillus Section Flavi in French Maize and Consequences on Aflatoxin Contamination of Maize at Harvest: Three-Year Survey

mycolabadmin

A harmful fungus called Aspergillus that produces cancer-causing toxins (aflatoxins) has become increasingly common in French maize crops over the past three years. Researchers collected and tested maize samples from across France and found that by 2020, about 80% of samples contained this fungus, and 16% had measurable levels of aflatoxins. This is happening because of hotter and drier conditions caused by climate change, which favor the fungus’s growth. The findings suggest that France needs to improve its monitoring and safety measures for maize to protect consumers and farmers.

Determination of Aflatoxins B1, B2, G1, and G2 concentrations in cheese puffs made from corn flour in Iran

mycolabadmin

Researchers tested 27 cheese puff snack packages from three popular Iranian brands to check for aflatoxin contamination. Aflatoxins are harmful toxins produced by mold that can contaminate corn-based foods. All samples showed detectable aflatoxin levels, but fortunately, none exceeded the safe limits set by Iran or the European Union. However, experts recommend continuous monitoring of these products because even low-level aflatoxin exposure over time could harm health, especially in children who consume these snacks frequently.
