“…The effective methods to manage mycotoxin contamination include application of antagonistic microbes to prevent mycotoxin production before harvest and using detoxification agents to treat contaminated foodstuffs (Atanasova-Penichon et al, 2016 ; Perczak et al, 2016 ; De Saeger and Logrieco, 2017 ). Due to its potentials to control plant pathogens, the non-toxigenic Trichoderma genus has been intensively investigated (Benítez et al, 2004 ).…”

Fungi belonging to Fusarium genus can infect crops in the field and cause subsequent mycotoxin contamination, which leads to yield and quality losses of agricultural commodities. The mycotoxin zearalenone (ZEN) produced by several Fusarium species (such as F. graminearum and F. culmorum) is a commonly-detected contaminant in foodstuffs, posing a tremendous risk to food safety. Thus, different strategies have been studied to manage toxigenic pathogens and mycotoxin contamination. In recent years, biological control of toxigenic fungi is emerging as an environment-friendly strategy, while Trichoderma is a fungal genus with great antagonistic potentials for controlling mycotoxin producing pathogens. The primary objective of this study was to explore the potentials of selected Trichoderma isolates on ZEN-producing F. graminearum, and the second aim was to investigate the metabolic activity of different Trichoderma isolates on ZEN. Three tested Trichoderma isolates were proved to be potential candidates for control of ZEN producers. In addition, we reported the capacity of Trichoderma to convert ZEN into its reduced and sulfated forms for the first time, and provided evidences that the tested Trichoderma could not detoxify ZEN via glycosylation. This provides more insight in the interaction between ZEN-producing fungi and Trichoderma isolates.

“…The elevated degree of contamination of feedstuffs by these microorganisms has resulted in significant losses to enterprises as these microorganisms generate mycotoxins on a massive scale, in addition to the decay of the raw materials. Aspergillus carbonarius and Aspergillus niger produce ochratoxin A trough their secondary metabolism [43].…”

Mycotoxins are known worldwide as fungus-produced toxins that adulterate a wide heterogeneity of raw feed ingredients and final products. Consumption of mycotoxins-contaminated feed causes a plethora of harmful responses from acute toxicity to many persistent health disorders with lethal outcomes; such as mycotoxicosis when ingested by animals. Therefore, the main task for feed producers is to minimize the concentration of mycotoxin by applying different strategies aimed at minimizing the risk of mycotoxin effects on animals and human health. Once mycotoxins enter the production chain it is hard to eliminate or inactivate them. This paper examines the most recent findings on different processes and strategies for the reduction of toxicity of mycotoxins in animals. The review gives detailed information about the decontamination approaches to mitigate mycotoxin contamination of feedstuffs and compound feed, which could be implemented in practice.

“…The challenges presented in mycotoxin research are enormous due to the frequency, the complexity and variability in occurrence. Several aspects make the pre-and post-harvest control of mycotoxins difficult, such as: Different fungal species produce mycotoxins, most of the mycotoxin producing fungi are able to produce more than one mycotoxin, mycotoxin levels are influenced by environmental conditions during growth and storage, the presence of modified mycotoxins and the highly complex influence of environmental factors on the biosynthesis of mycotoxins by fungi (De Saeger et al 2017). Other aspects related to human and animal health also contribute to the complexity in mycotoxin research, e.g.…”

Fungi have a long and intimate connection with humankind, particularly at the chemical level as a source of both harmful and beneficial compounds. Their worldwide occurrence in various food and feeds poses a major health threatening risk for human and animal and, as a consequence, mycotoxins represent an economic burden. Fortunately, not all fungal secondary metabolites are toxic to humankind such as; antibiotics, phytotoxines, enzymes and antioxidants, which represent the other side of the coin. Endophytes are now considered as an important component of biodiversity, and act as reservoirs of novel bioactive secondary metabolites, such as alkaloids, flavanoids, phenols, phenolic acids, quinones, steroids, saponins, tannins, terpenoids, isocoumarin derivatives, peptides and enzymes, beside their ability to produce the same or similar kind of compounds of their host plants. Today's world challenge is ensuring the safety of food, which has been a major focus of international and national action over the last years. Legislative limits for a range of mycotoxins continue to develop worldwide, due to being carcinogenic to animals and humans, resulting in an increased number of official controls monitoring in the food supply chain deriving from national food safety plans and for food trade purposes. This review brings about the harmful (mycotoxins) and beneficial (antioxidants, antibiotics, enzymes) fungal metabolites in industrial and pharmaceutical applications. It also provides a perspective about mechanism of how can endophytic fungi metabolites play a reverse role as one of the main strategies of mycotoxin deactivation and prevention representing the other side of the coin.
