Abstract
Durum wheat is one of the cereal crops that accumulates the highest concentrations of cadmium (Cd) and deoxynivalenol (DON) mycotoxin in its grains, thereby affecting the safety of products made of durum wheat grains (pasta and semolina). This study investigates in planta the interaction between Cd and Fusarium graminearum, the main causal agent of DON accumulation in grains. A pot experiment was designed to characterize the response of durum wheat to F. graminearum infection at three levels of Cd exposure: 0.1, 2, and 10 mg Cd kg-1 soil, which showed that the accumulation of Cd and DON resulted from interacting processes. On the one hand, plant exposure to Cd reduced the concentration of DON in grains. The mitigating effect of Cd on DON accumulation was attributed to the restricted growth of F. graminearum, which could result from enhanced plant resistance to the fungal pathogen induced by Cd exposure. On the other hand, F. graminearum infection of durum wheat increased the Cd concentration in the grains. The promoting effect of Fusarium infection on Cd accumulation was attributed to decoupling of the allocation of Cd and photoassimilates to the grains and to the reduced strength of the grain sink for photoassimilates caused by the fungus. Provided that this result is confirmed in field conditions, it suggests that in Cd-contaminated soils, particular attention should be paid to agronomic practices that affect Fusarium head blight disease to avoid further increase in the risk of exceeding the regulatory limit set by the European Union for Cd in durum wheat.

Characterization of Fusarium acuminatum: A Potential Enniatins Producer in Tunisian Wheat. J Fungi (Basel) 2022; 8:jof8050458.

Abstract
Fusarium Head Blight (FHB), caused by multiple species of Fusarium in small grain cereals, is a significant and long-standing problem anywhere in the world. Knowing regional Fusarium spp. present on non-symptomatic grains and their potential for mycotoxin production is of concern for identifying novel actions for FHB and mycotoxin management, such as treatments with essential oils. Analyzing the mycotoxin content of grains from non-symptomatic ears of different wheat varieties cultivated in Tunisia, we isolated Fusaria specimens identified as F. culmorum and F. acuminatum using analysis of the partial DNA sequence of the β-tubulin gene and ITS region. Two isolates of the latter species, uncommon in cereal grains in this region until now, were shown to be effective producers of enniatins in vitro, with 1390 and 3089 µg g−1 mycelial biomass (dry) in 11-day-old cultures. The susceptibility of an isolate of F. acuminatum to the fungistatic and antimycotoxin effects of eight essential oils was measured. Essential oils from Ammoides pusilla and Thymus capitatus used at 0.1 µL mL−1 in an agar culture medium, affected the mycelial growth by 55% and 79%, respectively and reduced the accumulation of enniatins per unit of mycelial colony by 26% and 52%, respectively. Finally, F. acuminatum was shown to be a contaminant of wheat grains in Tunisia and it may contribute to the contamination in enniatins. Two essential oils of Tunisian plants could be used for developing a biofungicide limiting both its mycelial growth and its accumulation of mycotoxins in grains.

Abstract
Mycotoxins are naturally present in cereal-based feed materials; however, due to adverse effects on animal health, their presence in derived animal feed should be minimized. A systematic literature search was conducted to obtain an overview of all factors from harvest onwards influencing the presence and concentration of mycotoxins in cereal-based feeds. The feed production processes covered included the harvest time, post-harvest practices (drying, cleaning, storage), and processing (milling, mixing with mycotoxin binders, extrusion cooking, ensiling). Delayed harvest supports the production of multiple mycotoxins. The way feed materials are dried after harvest influences the concentration of mycotoxins therein. Applying fungicides on the feed materials after harvest as well as cleaning and sorting can lower the concentration of mycotoxins. During milling, mycotoxins might be redistributed in cereal feed materials and fractions thereof. It is important to know which parts of the cereals are used for feed production and whether or not mycotoxins predominantly accumulate in these fractions. For feed production, mostly the milling fractions with outer parts of cereals, such as bran and shorts, are used, in which mycotoxins concentrate during processing. Wet-milling of grains can lower the mycotoxin content in these parts of the grain. However, this is typically accompanied by translocation of mycotoxins to the liquid fractions, which might be added to by-products used as feed. Mycotoxin binders can be added during mixing of feed materials. Although binders do not remove mycotoxins from the feed, the mycotoxins become less bioavailable to the animal and, in the case of food-producing animals, to the consumer, lowering the adverse effects of mycotoxins. The effect of extruding cereal feed materials is dependent on several factors, but in principle, mycotoxin contents are decreased after extrusion cooking. The results on ensiling are not uniform; however, most of the data show that mycotoxin production is supported during ensiling when oxygen can enter this process. Overall, the results of the literature review suggest that factors preventing mycotoxin production have greater impact than factors lowering the mycotoxin contents already present in feed materials.

Abstract
The study aimed to investigate the effect of technological processes on deoxynivalenol (DON), 3-acetyl-deoxynivalenol (3-ADON) and 15-acetyl-deoxynivalenol (15-ADON) concentrations and quality of spring wheat products from grain harvested at different times. In this study, 408 samples were analysed for DON, 3-ADON and 15-ADON contamination by the HPLC method with UV detection. Delays in harvesting due to cool and rainy weather conditions resulted in increased DON, 3-ADON and 15-ADON levels. The highest DON concentrations were determined in bran. Higher DON concentrations in the bran indicate the protective function of the grain hull. On the other hand, the highest levels of minerals have been found in bran and whole grain flours, highlighting the importance of consuming these milling fractions as a mineral source with sustained health benefits. Our results showed that DON is stable at 170 °C, and high DON levels in whole-meal flour and white flour could not be converted or decomposed during baking. The levels of 3-ADON and 15-ADON in whole-meal flour bread and white flour bread were significantly reduced but not completely removed. The levels of DON and its derivatives 3-ADON and 15-ADON were significantly reduced in starch and gluten produced from contaminated whole meal flour; however, the washing process did not completely eliminate these toxic compounds. The concentrations of mycotoxins in starch and gluten remained relatively high. Negative correlation was found in highly contaminated samples between DON and bread baking properties. Also, inverse relationship was found between high mycotoxin concentrations and mineral element content in white flour.

Abstract
Consumption of cereals contaminated by mycotoxins poses health risks. For instance, Fumonisins B, mainly produced by Fusarium verticillioides and Fusariumproliferatum, and the type B trichothecene deoxynivalenol, typically produced by Fusarium graminearum, are highly prevalent on cereal grains that are staples of many cultural diets and known to represent a toxic risk hazard. In Peru, corn and other cereals are frequently consumed on a daily basis under various forms, the majority of food grains being sold through traditional markets for direct consumption. Here, we surveyed mycotoxin contents of market-bought grain samples in order to assess the threat these mycotoxins might represent to Peruvian population, with a focus on corn. We found that nearly one sample of Peruvian corn out of six was contaminated with very high levels of Fumonisins, levels mostly ascribed to the presence of F. verticillioides. Extensive profiling of Peruvian corn kernels for fungal contaminants could provide elements to refine the potential risk associated with Fusarium toxins and help define adapted food safety standards.

Abstract
With 744 million metric tons produced in 2017/2018, bread wheat (Triticum aestivum) and durum wheat (Triticum durum) are the second most widely produced cereal on a global basis. Prevention or control of wheat diseases may have an enormous impact on global food security and safety. Fusarium head blight is an economically debilitating disease of wheat that reduces the quantity and quality of grain harvested, and may lead to contamination with the mycotoxin deoxynivalenol, which affects the health of humans and domesticated animals. Current climate change scenarios predict an increase in the number of epidemics caused by this disease. Multiple strategies are available for managing the disease including cultural practices, planting less-susceptible cultivars, crop rotation, and chemical and biological controls. None of these strategies, however, is completely effective by itself, and an integrated approach incorporating multiple controls simultaneously is the only effective strategy to limit the disease and reduce deoxynivalenol contamination in human food and animal feed chains. This review identifies the available tools and strategies for mitigating the damage that can result from Fusarium head blight.

Abstract
Wheat grains collected in three regions of Russia—Volga, Ural, and West Siberia—were analyzed for triangulation of methods in analysis of toxigenic Fusarium species. The presence of fungi and quantitative content of their biomass were detected by using various analytical methods, including a mycological and immunochemical methods, and quantitative PCR. Additionally, an enzyme-linked immunosorbent assay and high-performance liquid chromatography with tandem mass spectrometry were applied for determination of mycotoxins. Regional differences were found regarding the contamination of wheat grain by Fusarium fungi and their toxins. The most important observation was the detection of F. graminearum in the Ural and West Siberian regions, where this pathogen had not been found previously. A maximum damaged grains by F. graminearum and F. sporotrichioides was found in the grain samples from West Siberia. The DNA of F. graminearum was detected in 19.2% and DNA of F. sporotrichioides was found in 84.1% of the analyzed grain samples. The amount of Fusarium antigens in the grain samples from the West Siberian region was 7–8 times higher than in the grain samples from the other two regions. Significant contamination of the grain with deoxynivalenol and T-2/HT-2 toxins (maximum contents were 2239 ppb and 199 ppb, respectively) was detected in the West Siberian region.

Abstract
Milling and sifting of grain are important processes that affect mycotoxin distribution in the chain of grain products. The level of deoxynivalenol (DON) in white flour cannot be reduced by sifting because it is concentrated within a specific white flour fraction. The objective of this study was to investigate the influence of milling and sifting processes on the reduction of DON contamination in whole-wheat flour and in the chain of spring wheat products (grain – bran – white flour – white flour fractions) from artificially and naturally (2016) and naturally (2017) infected grain samples. The current study showed that the distribution of DON in the grain products (whole-wheat flour – bran – white flour) depends on the weather conditions of the season and grain contamination level. This was particularly evident in the naturally contaminated grain in 2017. The highest DON concentrations were determined in bran. Higher DON concentrations in the bran from the naturally infected grain indicate the protective function of the grain hull, which provides partial protection for grain embryo against higher contamination. With a delay in harvesting, which resulted in increased DON concentrations, bran remained the most contaminated product; however, this was not true for the products from artificially infected grain. The DON level in bran was not significantly different at P<0.05 from that in whole-wheat flour from artificially infected grain, it indicates that after inoculation, bran had biochemical compounds capable of significantly diminishing trichothecene production. It was investigated that DON levels were concentrated in white flour fractions 160 and 112 μm from naturally infected grains and in white flour fraction (residues) from artificially and naturally infected grains harvested later. The results obtained in this study could be further used for developing novel strategies aimed at limiting mycotoxin contamination in food and feed.

Abstract
Mycotoxins are a potential health threat in cereals including wheat. In the European Union (EU), mycotoxin maximum levels are laid down for cereal raw materials and final food products. For wheat and wheat-based products, the EU maximum levels apply to deoxynivalenol (DON), zearalenone, aflatoxins, and ochratoxin A. This review provides a comprehensive overview on the different mycotoxins and their legal limits and on how processing of wheat can affect such contaminants, from raw material to highly processed final products, based on relevant scientific studies published in the literature. The potential compliance with EU maximum levels is discussed. Of the four mycotoxins regulated in wheat-based foods in the EU, most data are available for DON, whereas aflatoxins were rarely studied in the processing of wheat. Furthermore, available data on the effect of processing are outlined for mycotoxins not regulated by EU law-including modified and emerging mycotoxins-and which cover DON derivatives (DON-3-glucoside, mono-acetyl-DONs, norDONs, deepoxy-DON), nivalenol, T-2 and HT-2 toxins, enniatins, beauvericin, moniliformin, and fumonisins. The processing steps addressed in this review cover primary processing (premilling and milling operations) and secondary processing procedures (such as fermentation and thermal treatments). A special focus is on the production of baked goods, and processing factors for DON in wheat bread production were estimated. For wheat milling products derived from the endosperm and for white bread, compliance with legal requirements seems to be mostly achievable when applying good practices. In the case of wholemeal products, bran-enriched products, or high-cereal low-moisture bakery products, this appears to be challenging and improved technology and/or selection of high-quality raw materials would be required.

Abstract
Fusarium proliferatum produces fumonisins B not only on maize but also on diverse crops including wheat. Using a wheat-based medium, the effects of abiotic factors, temperature and water activity (aW), on growth, fumonisin biosynthesis, and expression of FUM genes were compared for three F. proliferatum strains isolated from durum wheat in Argentina. Although all isolates showed similar profiles of growth, the fumonisin production profiles were slightly different. Regarding FUM gene transcriptional control, both FUM8 and FUM19 expression showed similar behavior in all tested conditions. For both genes, expression at 25°C correlated with fumonisin production, regardless of the aw conditions. However, at 15°C, these two genes were as highly expressed as at 25°C although the amounts of toxin were very weak, suggesting that the kinetics of fumonisin production was slowed at 15°C. This study provides useful baseline data on conditions representing a low or a high risk for contamination of wheat kernels with fumonisins.

Abstract
Levels of lutein and a number of mycotoxins were determined in seven varieties of durum wheat (Triticum durum) and two varieties of common wheat (Triticum aestivum) in order to explore possible relationships amongst these components. Durum wheat cultivars always showed both higher lutein and mycotoxin contents than common wheat cultivars. The mycotoxins detected in both common and durum wheat cultivars were produced by the genera Fusarium, Claviceps, Alternaria and Aspergillus. Fusarium was the major producer of mycotoxins (26 mycotoxins) followed by Claviceps (14 mycotoxins), which was present only in some cultivars such as Chevalier (common wheat), Lupidur and Selyemdur (both durum wheat), Alternaria (six mycotoxins) and Aspergillus (three mycotoxins). Positive correlations between the levels of lutein and mycotoxins in durum wheat cultivars were found for the following mycotoxins: deoxynivalenol (DON), its derivative DON-3-glucoside, moniliformin, culmorin and its derivatives (5-hydroxyculmorin and 15-hydroxyculmorin).

Abstract
The milling behaviour of two naturally infected samples of durum wheat grain with contrasting levels of mycotoxins was studied. Although the two samples showed a similar milling behaviour, an increase of approximately 20% in deoxynivalenol (DON) levels was found in semolina from the sample containing the higher level of mycotoxin. However, even if the highest concentration of DON was found in fractions originating from the grain outer layers, the mycotoxin contamination in semolina and flours were not related to the amount of two compounds (ash or phytic acid) used to monitor these external tissues. The presence of the trichothecene-producing fungi in the inner-most semolina fraction was also shown using specific DNA primers and PCR amplification. Comparison of DON concentrations in the feed stock and corresponding output at each milling step or grinding of semolina fractions followed by sizing showed that concentration of mycotoxin occurs in the finest particles at the first processing steps. Therefore, DON contamination of milling fractions is not simply due to the presence of peripheral grain tissues.

Ferulic acid, an efficient inhibitor of type B trichothecene biosynthesis and Tri gene expression in Fusarium liquid cultures. ACTA ACUST UNITED AC 2009; 113:746-53.

Abstract
The effect of ferulic acid, the most abundant phenolic acid in wheat bran, was studied in vitro on type B trichothecene biosynthesis by Fusarium. It was demonstrated that ferulic acid is an efficient inhibitor of mycotoxin production by all strains of Fusarium tested, including different chemotypes and species. To analyse the mechanism of toxin biosynthesis inhibition by ferulic acid, expression of representative Tri genes, involved in the trichothecene biosynthesis pathway, was monitored by real-time RT-PCR. A decrease in the level of Tri gene expression was measured, suggesting that inhibition of toxin synthesis by ferulic acid could be regulated at the transcriptional level. Moreover, toxin production was shown to be reduced proportionally to the initial amount of ferulic acid added in the culture medium. Addition of ferulic acid either at the spore germination step or to a mycelial culture resulted in the same final inhibitory effect on mycotoxin accumulation. A cumulative inhibitory effect on trichothecene biosynthesis was even observed with successive supplementation of ferulic acid. Ferulic acid, which content varies among wheat varieties, could then play an important role in modulating trichothecene biosynthesis by Fusarium in some wheat varieties.

Abstract
Mycotoxins are secondary metabolites produced by filamentous fungi which have toxicologically relevant effects on vertebrates if administered in small doses via a natural route. In order to improve food safety and to protect consumers from harmful contaminants, the presence of fungi with the potential to produce such compounds must be checked at critical control points during the production of agricultural commodities as well as during the process of food and feed preparation. Polymerase chain reaction (PCR)-based diagnosis has been applied as an alternative assay replacing cumbersome and time-consuming microbiological and chemical methods for the detection and identification of the most serious toxin producers in the fungal genera Fusarium, Aspergillus, and Penicillium. The current chapter covers the numerous PCR-based assays which have been published since the first description of the use of this technology to detect Aspergillus flavus biosynthesis genes in 1996.

Abstract
Effect of exogenous H(2)O(2) and catalase was tested in liquid cultures of the deoxynivalenol and 15-acetyldeoxynivalenol-producing fungus Fusarium graminearum. Accordingly to previous results, H(2)O(2) supplementation of the culture medium leads to increased toxin production. This study indicates that this event seems to be linked to a general up regulation of genes involved in the deoxynivalenol and 15-acetyldeoxynivalenol biosynthesis pathway, commonly named Tri genes. In catalase-treated cultures, toxin accumulation is reduced, and Tri genes expression is significantly down regulated. Furthermore, kinetics of expression of several Tri genes is proposed in relation to toxin accumulation. Biological meanings of these findings are discussed.
