Fungi are widely disseminated in the environment and are major food contaminants, colonizing plant tissues throughout the production chain, from preharvest to postharvest, causing diseases. As a result, grain development and seed germination are affected, reducing grain quality and nutritional value. Some fungal species can also produce mycotoxins, toxic secondary metabolites for vertebrate animals. Natural compounds, such as essential oils, have been used to control fungal diseases in cereal grains due to their antimicrobial activity that may inhibit fungal growth. These compounds have been associated with reduced mycotoxin contamination, primarily related to reducing toxin production by toxigenic fungi. However, little is known about the mechanisms of action of these compounds against mycotoxigenic fungi. In this review, we address important information on the mechanisms of action of essential oils and their antifungal and antimycotoxigenic properties, recent technological strategies for food industry applications, and the potential toxicity of essential oils.

Wheat plants are impacted by Fusarium head blight (FHB) infection, which poses a huge threat to wheat growth, development, storage and food safety. In this study, a fungal strain was isolated from diseased wheat plants and identified as Fusarium asiaticum F1, known to be a member of the Fusarium graminearum species complex, agents causally responsible for FHB. In order to control this disease, new alternatives need to be developed for the use of antagonistic bacteria. Bacillus velezensis E2 (B. velezensis E2), isolated from a previous investigation in our laboratory, showed a notable inhibitory effect on F. asiaticum F1 growth and deoxynivalenol (DON) synthesis in grains. The spore germination of F. asiaticum F1 was significantly reduced and the spores showed vesicular structures when treated with B. velezensis E2. Observations using scanning electron microscopy (SEM) showed that the hyphae of F. asiaticum F1 were shrunken and broken when treated with B. velezensis E2. The RNA-seq results of F1 hyphae treated with B. velezensis E2 showed that differentially expressed genes (DEGs), which were involved in multiple metabolic pathways such as toxin synthesis, autophagy process and glycan synthesis, especially the genes associated with DON synthesis, were significantly downregulated. In summary, those results showed that B. velezensis E2 could inhibit F. asiaticum F1 growth and reduce the gene expression of DON synthesis caused by F1. This study provides new insights and antagonistic mechanisms for the biological control of FHB during wheat growth, development and storage.

“…Multiple documents have reported that Fusarium species are responsible for the production of several mycotoxins, e.g., fumonisins, trichothecenes, zearalenone, enniatins, and fusaproliferin (Munkvold 2017;Jajić et al 2019;Gautier et al 2020). Recently, Choi et al (2021) reported the presence of Fusarium spp. in millet samples with the highest frequency of mycotoxin being F. asiaticum, followed by F. acuminatum, F. graminearum, F. incarnatum, F. equiseti, and F. tricinctum besides other species of Fusarium.…”

Garlic (Allium sativum L.) being infected by mycotoxigenic fungi is one of the primary factors limiting its nutritional and medical value. Therefore, there is an urgent need to repress mycotoxigenic fungi utilizing safer treatments, possibly involving nanoparticles. Fusarium incarnatum was isolated from garlic (A. sativum L.) that showed fungal contamination and their identification was confirmed using amplified and sequenced internal transcribed spacer nuclear ribosomal DNA regions, which confirmed the isolation of F. incarnatum from all cultivars. Copper oxide nanoparticles (CuONPs) at different concentrations showed inhibitory activity against F. incarnatum growth and mycotoxins, particularly at 400 ppm. The production of F. incarnatum mycotoxins, i.e., beauvericins, fusarins, moniliformin, and enniatins, was inhibited to 62.8%, 45.4%, 58.1%, and 55.0%, respectively at 400 ppm of CuONPs compared to the control. Shrinkage of the F. incarnatum cell membrane and collapsing of the cell walls were recorded via transmission electron microscopy at 400 ppm, but negligible distortion appeared at 100 ppm of CuONPs. CuONPs at 100 ppm encouraged the activity of CMC-ase, zylanase, and amylase, while 200 and 400 ppm promoted less enzyme activity. The current findings suggest that CuONPs have a fungistatic effect on F. incarnatum and their mycotoxins.
