is a major aflatoxin B, posing significant health concerns to humans, crops, and producer fungi. Due to the undesirable consequences of the usage of synthetic fungicides, biological control using yeasts has gained more attention. In this study, eight isolates of epiphytic yeasts belonging to sp., sp. and sp., which have been identified as antagonists, were isolated from different plants, including grapes, blueberries, hawthorns, hoşkıran, beans and grape leaf. While volatile organic compounds (VOCs) produced by DN-FY, aff. DN-MP and aff. 32-AMM reduced in vitro mycelial growth and sporulation, only VOCs produced by aff. 1-UDM were found to be effective at reducing in vitro AFB production. All yeasts reduced the mycelial growth of by 76-91%, while AFB production reduced to 1.26-10.15 ng/g and the control plates' growth was 1773 ng/g. The most effective yeast, aff. DN-HS, reduced growth and aflatoxin B production on hazelnuts. The AFB content on hazelnuts reduced to 333.01 ng/g from 536.74 ng/g. To our knowledge, this is the first report of yeasts isolated from plants being tested as potential biological control agents to reduce AFB production on hazelnuts.

Most of the excessive aflatoxins in peanut oil are present at lower levels, and few photocatalysts have been reported for degrading low concentrations of aflatoxin B (AFB). This study employed aptamer-modified magnetic graphene oxide/titanium dioxide (MGO/TiO-aptamer) photocatalysts to degrade low concentrations of AFB in peanut oil, thoroughly investigating their selective efficiency, degradation mechanism, and product toxicity. The results indicated that the modification of aptamers on the surface of photocatalytic materials can enhance the selectivity of photocatalysts for AFB in peanut oil.

Aflatoxin B is a prevalent secondary hazardous metabolite generated by fungus present in feed ingredients and the surrounding environment: enzymes are currently being recognized as an efficient and promising approach to reducing the associated risks. The objective of this study was to assess the effects of varying doses of enzyme complexes on several parameters in laying hens that were exposed to aflatoxin. During an 8-week experiment, a total of 288 Yukou Jingfen No.

Feed quality is among the most determinative criteria for aquaculture success. Along with feed ingredient quality and its production process, feed storage conditions would also affect feed quality, especially in terms of adventitious toxins. Mycotoxins are frequent food and feed contaminants and are considered important health threats to both human and animal health.

Groundnuts are considered as one of the most important cultivated food crops globally. Groundnuts are used for vegetable oil production, which generate a variety of by-products, such as peanut press cake (PPC). Groundnuts are sensitive to infection by aflatoxigenic fungi.
