Aflatoxin Biodetoxification Strategies Based on Postbiotics.

Aflatoxins (AFs) are secondary metabolites produced by fungi, and they are deemed the most perilous mycotoxin and food safety predicament. The exposure of humans to mycotoxins transpires either directly through the consumption of contaminated agricultural commodities or indirectly through the ingestion of items derived from animals that have been nourished with tainted substances of animal origin. To ensure the detoxification of AFs in animal and plant food products and to mitigate the risks they pose to public health and the economy, diverse techniques (physical, chemical, and biological) have been subject to scrutiny. By altering and eradicating the molecular structure of the toxin, all of these approaches impede its transmission to the digestive system and potentially diminish the accessibility of toxins to the target tissue, ultimately eliminating them. Given the pervasive predicaments attributed to the contamination of foods and feeds by AFs, it is of utmost importance to urgently devise cost-effective and appropriate strategies to combat this hazard. This review highlights the concept of AFs, definitions, and benefits of postbiotics and their biological role in the detoxification of AFs, as well as their benefits in the food-pharmaceutical industry.

Postbiotics as Potential Detoxification Tools for Mitigation of Pesticides.

Pesticides possess a pivotal role in the realm of agriculture and food manufacturing, as they effectively manage the proliferation of weeds, insects, plant pathogens, and microbial contaminations. They are valuable in some ways, but if misused, they can cause health issues like cancer, reproductive toxicity, neurological illnesses, and endocrine system disturbances. In this regard, practical methods for reducing pesticide residue in food should be used. For reducing pesticide residue in food processing, some strategies have been suggested. Recent research has been done on detoxification processes, including microorganisms like probiotics and their metabolites. The term "postbiotics" describes soluble substances, such as peptides, enzymes, teichoic acids, muropeptides generated from peptidoglycans, polysaccharides, proteins, and organic acids that are secreted by living bacteria or released after bacterial lysis. Due to their distinct chemical makeup, safe dosage guidelines, lengthy shelf lives, and presence of various signaling molecules that may have antioxidant, anti-inflammatory, anti-obesogenic, immunomodulatory, anti-hypertensive, and immunomodulatory effects, these postbiotics have attracted interest. They also can detoxify heavy metals, mycotoxins, and pesticides. Hydrolytic enzymes have been proposed as a potential mechanism for pesticide degradation. Postbiotics can also reduce reactive oxygen species production, enhance gastrointestinal barrier function, reduce inflammation, and modulate host xenobiotic metabolism. This review highlights pesticide residues in food products, definitions and safety aspect of postbiotics, as well as their biological role in detoxification of pesticides and the protective role of these compounds against the adverse effects of pesticides.

Postbiotics as potential promising tools for SARS-CoV-2 disease adjuvant therapy.

The SARS-CoV-2 pandemic defines the global health tension of our time. There are several continuous efforts to find a definitive cure in this regard. According to some adverse effects and problems of customary SARS-CoV-2 disease therapies, bioactive compounds, for example probiotics-derived metabolites (postbiotics) have been accomplishing supreme importance by investigators for adjuvant cures in patients with SARS-CoV-2. Postbiotics inhibit angiotensin-converting enzyme 2 activity and stimulate the immune system. They also boost the SARS-CoV-2 disease treatment effectiveness and reduce its adverse effects in SARS-CoV-2 illness patients as a result of antiviral and anti-inflammatory effects. Furthermore, postbiotics having unique features such as high safety, high shelf life and stability to the gastrointestinal tract can be utilized as hopeful instruments for both adjuvant and inhibition strategies in SARS-CoV-2 patients with no earnest unfavourable adverse effects. The concept of postbiotics and their biocompatible characteristics are comprehensively discussed in the present review while highlighting the bilateral relationship between postbiotic biometabolites and respiratory tract infection with a special look at the potential biological role in the inactivation of SARS-CoV-2 and reduction of related inflammatory pathways.
