“…In a similar study, the addition of AgNP HA1N, AgNP HA2N, and AgNP EH resulted in 88.2%, 67.7% and 83.5% reduction of AFB1 synthesized by A. flavus [172]. Also, the fungicidal activity of Capsicum annuum L. was recently reported [173]. The active ingredient could be isolated and encapsulated in NPs, which may exhibit potent inhibitory activities against storage pest and microorganism.…”

Cereals and legumes are the major staples across the globe, thus providing nutrition to humans, and their by-products utilized as animal feeds. However, mycotoxins synthesized by fungi contaminate these grains on the field during cultivation and are transferred to the storage centers. These fungi infect and deteriorate stored grains, thereby tampering with food security. Moreover, the deterioration decreases nutrient content and alters the physicochemical properties of grains. The current conventional methods used to reduce grain contamination are becoming ineffecitive, coupled with the detrimental health effects it has on the consumer and to the environment. Herein, we present an overview of the use of nanoparticles (NPs) as an alternative and novel method of reducing mycotoxin biosynthesis due to their potent biocidal properties. Silver nanoparticles (AgNPs) are considered and have shown promising and effective fungicidal properties against important storage fungi, and pests hence could be utilized in the agriculture and food sector for a vast myriad of applications. These may help to either minimize/eradicate the exposure to the mycotoxins and its adverse health effects, hence contributing to the holistic growth and development of people.

“…Oxidative damage could have compromised spore viability, leading to an efficient inactivation. This result is in agreement with Dasan et al ., Yoshino et al ., 60 Go et al 51 . and Ambrico et al ., 53 who observed that fungal spores exposed to NTP can present aggregation, structural changes, cell wall and membrane disruption, etching, perforation, cracking and/or surface erosion.…”

“…The oxidative power of NTP, due to the production of ROS and RNS, has been extensively demonstrated, as has the ability of plasma to destroy microbial cells through oxidative damage. 51 Because ROS can cause severe damage to DNA, protein and lipids when present at high levels, organisms have evolved defense systems (non-enzymatic molecules and enzymatic scavengers) to cope with ROS accumulation. Because the fungal cell wall and cell membrane are the first structures to come into contact with plasma components, Šimončicová et al 20 related the morphological changes observed in the appearance of Aspergillus flavus colonies exposed to NTP to the effects of ROS on the fungal cell: erosion of the cell surface, desiccation of the cell wall, oxidation of cell wall polysaccharides and peroxidation of membrane lipids.…”

BACKGROUND The Diaporthe/Phomopsis complex (D/P) is a group of soybean seed‐borne fungi. The use of chemical fungicides, either for seed treatment or during the crop cycle, is the most adopted practice for treating fungal diseases caused by this complex. Worldwide, there is a search for alternative seed treatments that are less harmful to the environment than chemicals. Non‐thermal plasma (NTP) is a novel seed treatment technology for pathogen removal. This research aimed to evaluate the effects of NTP on the in vitro performance of pure cultures of Diaporthe longicolla and elucidate the mechanisms underlying these effects. RESULTS Active D. longicolla mycelium, growing in vitro, was exposed to different NTP treatments, employing a dielectric barrier discharge arrangement with different carrier gases (N2 or O2). Fungal growth, fresh biomass and colony appearance were negatively affected by plasma treatments (TN3 and TO3). Lipid peroxidation and antioxidant activities were higher in plasma‐treated colonies comparison with non‐exposed colonies (control). Fungal asexual spores (conidia) were also exposed to NTP, showing high susceptibility. CONCLUSION Exposure of D. longicolla colonies to NTP severely compromised fungal biology. Ozone production during treatment and lipid peroxidation of fungal cell membranes appeared to be involved in the observed effects. © 2020 Society of Chemical Industry

“…Since the e ciency of the washing and sanitation processes are directly related to the microbiological quality of the end-product, companies are interested in the continuous optimization of these processes (55,56). Investigations showed that plasma or PGCs do not cause any changes in the texture and color of the food and still cause a signi cant reduction in the bacterial contamination (57)(58)(59). Due to the fact that many plasma sources nowadays can be operated with ambient air and tap water as a treatment source for food, the process is cost e cient and ecological.…”

Plasma-generated compounds (PGCs) such as plasma-processed air (PPA) or plasma-treated water (PTW) offer an increasingly important alternative for the treatment of microorganisms in hard-to-reach areas found in several industrial applications including the food industry. To this end, we studied the antimicrobial capacity of plasma-treated water on the vitality and biofilm formation of Listeria monocytogenes, a common food spoilage microorganism. Using a microwave plasma (MidiPLexc), 10 ml of deionized water was treated for 100 s, 300 s and 900 s (pretreatment time) and the bacterial biofilm was subsequently exposed to the PTW for 1 min, 3 min and 5 min (posttreatment time) for each pretreatment time separately. Colony-forming units (CFU), metabolic activity, and cell vitality were reduced for 4.7 log10, 47.9%, and 69.5%, respectively. Live/dead staining and fluorescence microscopy showed a positive correlation between treatment and incubation times and reduction in vitality. Atomic force microscopy indicated a change in the plasticity of the bacteria. These results suggest a promising antimicrobial impact of plasma-treated water on Listeria monocytogenes, which may lead to more targeted applications of plasma decontamination in the food industry in the future.
