“…Du et al [10] found that most hydrolases and oxidases were inhibited by ZnONPs, such as: β-glucosidase, acid phosphatase, polyphenol oxidase and peroxidase. You et al [11] also found that similar results were obtained for the effects of ZnO, TiO2, CeO 2 and Fe 3 O 4 NPs on soil enzyme activities (invertase, urease, catalase, and phosphatase) and bacterial community in saline-alkali and black soil. However, the effects of ZnONPs on soil heterotrophic respiration, microbial biomass and enzyme activity under the addition of different exogenous organic matter have not been studied.…”

In order to investigate the effect of ZnO nanoparticles (ZnONPs) on soil ecosystem in soil with added cellulose and lignin, five treatments were set up: cellulose, cellulose + ZnONPs, lignin, lignin + ZnONPs, and no addition. The soil respiration, microbial biomass, and the activities of soil enzymes were explored during a 56-day incubation time after the addition of ZnONPs. The results showed that when cellulose and lignin were added to the soil, the CO2 efflux increased by 90.9% and 18.2%, respectively, compared with the control soil. The microbial biomass carbon and the activity of peroxidase, polyphenol oxidase, β-glucosidase and cellulase were increased. Compared with the treatment with the addition of cellulose and lignin only, the exposure of ZnONPs increased the CO2 efflux, microbial biomass carbon, β-glucosidase and cellulase activities, but decreased the peroxidase and polyphenol oxidase activities. We concluded that the addition of cellulose and lignin to farmland soil increased respiration, microbial biomass and soil enzyme activity, but the degradation degree of cellulose was higher than lignin. The ZnONPs promote soil respiration, microbial biomass, and hydrolase activity throughout the culture period, but inhibited the activity of redox enzymes.

“…Their use and release into the soil have an adverse effect on soil microbial ecology, modifying their number, biomass, activity, and diversity. MeNPs such as ZnO, TiO 2 , CeO 2 , and Fe 3 O 4 NPs affect soil enzyme activities and change soil bacterial communities [99]. Besides, CeO 2 NPs have been found to compromise soil fertility [100].…”

Viruses are estimated to be responsible for approximately 50% of the emerging plant diseases, which are difficult to control, and in some cases, there is no cure. It is essential to develop therapy practices to strengthen the management of these diseases caused by viruses in economically important crops. Metal nanoparticles (MeNPs) possess diverse physicochemical properties that allow for them to have a wide range of applications in industry, including nanomedicine and nano-agriculture. Currently, there are reports of favorable effects of the use of nanoparticles, such as antibacterial, antifungal, and antiviral effects, in animals and plants. The potential antiviral property of MeNPs makes them a powerful option for controlling these histological agents. It is crucial to determine the dosage of NPs, the application intervals, their effect as a biostimulant, and the clarification of the mechanisms of action, which are not fully understood. Therefore, this review focuses on discussing the ability of metal nanoparticles and metal oxides to control viruses that affect agriculture through an exhaustive analysis of the characteristics of the particles and their interaction processes for a possibly beneficial effect on plants.

“…The toxic effect of Cu-based NPs has been shown for beneficial soil microbes such as nitrifying bacteria, nitrogen-fixing bacteria, Arbuscular mycorrhiza and other Rhizobacteria; however, it also influences other microorganisms. You et al (2017) suggested that the soil types could play an important role in determining NPs toxicity over soil bacterial community composition and size. Recent studies showed that NPs might affect enzymatic and metabolic activities, nitrification potential, colony count and abundance of soil bacterial diversity (Colman et al 2013;Ge et al 2011;He et al 2016).…”
