“…In addition, as was observed on the PDA plates, the number of F. graminearum -infected grains was not significantly ( p > 0.05) different between the treated and untreated samples incubated on the WA medium ( Table 4 , Figure 2 ). In a previous study, the growth of F. graminearum was significantly inhibited following PAW treatment of F. graminearum in culture [ 1 ]. Moreover, the growth rate of F. graminearum was significantly ( p < 0.05) reduced after treating the fungus with gliding arc plasma [ 36 ].…”

“…The RONS and radicals from PAW can react with the cell walls of fungi and result in the oxidation of the cell wall components such as glucose, (N-acetyl)-glucosamine, glycoproteins and glucan, and peroxidation of the lipids in the plasma membrane. This will result in the damage and perforation of the cell wall and membrane, and subsequent exposure of the intracellular components to RONS [ 1 ]. Different parameters in PAW, such as type and concentration of RONS and pH of PAW, can influence the growth of microflora.…”

“…The contamination of agricultural products with fungi and their secondary metabolites (mycotoxins) creates major challenges for the food industry. Fusarium graminearum is an ascomycete fungus that causes fusarium head blight in wheat and barley [ 1 ]. F. graminearum produces deoxynivalenol (DON), a type b trichothecene mycotoxin [ 2 ], and the consumption of foods contaminated with DON can affect animal and human health, causing nausea, vomiting, headaches, diarrhea, dizziness, fever, and other acute or chronic toxicities [ 3 ].…”

“…Furthermore, if DON is present in the barley grains, it may end up in the final products, if the barley malting unit operations cannot degrade this mycotoxin. The antifungal properties of PAW have been previously reported [ 1 , 8 ]. In a recent study by Guo, Wang, Xie, Jiang, Li, Li, Li, Liu and Lin [ 1 ], microbial activity of F. graminearum spores, including mycelial growth, conidial germination, and disease development, were significantly inhibited by PAW treatment of spiked wheat samples.…”

Contamination of barley by deoxynivalenol (DON), a mycotoxin produced by Fusarium graminearum, causes considerable financial loss to the grain and malting industries. In this study, two atmospheric cold plasma (ACP) reactors were used to produce plasma-activated water (PAW) bubbles. The potential of PAW bubbles for the steeping of naturally infected barley (NIB) during the malting process was investigated. The PAW bubbles produced by treating water for 30 min using a bubble spark discharge (BSD) at low temperature resulted in the greatest concentration of oxygen-nitrogen reactive species (RONS). This treatment resulted in 57.3% DON degradation compared with 36.9% in the control sample; however, the same treatment reduced germination significantly (p < 0.05). Direct BSD ACP treatment for 20 min at low temperature and indirect treatment for 30 min increased the percentage of germinated rootlets of the seedlings compared with the control. Considering both the DON reduction and germination improvement of barley seeds, continuous jet ACP treatment for 30 min performed better than the other treatments used in this study. At higher temperature of PAW bubbles, the concentration of RONS was significantly (p < 0.05) reduced. Based on quantitative polymerase chain reaction (qPCR) analysis and fungal culture tests, the PAW bubble treatment did not significantly reduce infection of NIB. Nonetheless, this study provides useful information for the malting industry for PAW treatment optimization and its use in barley steeping for DON reduction and germination improvement.

Over the last decade, more and more attention has been paid to applications of non-thermal plasma in agriculture, where it is used to decontaminate various microorganisms and to improve the seed germination. In this study, we present the results of a newly developed point-to-ring NTP transient spark discharge apparatus (NTP), plasma activated water (PAW) and their combined treatment on Durum wheat and Common wheat grains under laboratory conditions. Transient spark discharge treatment was used as direct treatment while indirect treatment of wheat grains was performed by PAW produced in point-to-plane NTP transient spark apparatus. We found that the degree of grain surface decontamination was in order NTP > PAW > combined treatment. In the case of Durum wheat grain germination, all treatments increased germination with increasing exposure times, while in the case of Common wheat, PAW treatment and combined treatment did not significantly increase the grain germination. In conclusion, plasma treatment has enormous potential for use in agriculture and its possibilities need to be fully explored.
