“…Furthermore, the elemental percentage of CSNPs in this study is similar to the report of Sotelo et al [ 50 ], while the elemental percentage of ZnONPs of this study is similar to the report of Ogunyemi et al [ 19 ]. In agreement with the result of Ali et al [ 51 ], the EDS analysis obtained in this study shows that the samples prepared using aqueous green tomato extract contained pure ZnONPs.…”

Bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most devastating diseases, resulting in significant yield losses in rice. The extensive use of chemical antibacterial agents has led to an increase the environmental toxicity. Nanotechnology products are being developed as a promising alternative to control plant disease with low environmental impact. In the present study, we investigated the antibacterial activity of biosynthesized chitosan nanoparticles (CSNPs) and zinc oxide nanoparticles (ZnONPs) against rice pathogen Xoo. The formation of CSNPs and ZnONPs in the reaction mixture was confirmed by using UV-vis spectroscopy at 300–550 nm. Moreover, CSNPs and ZnONPs with strong antibacterial activity against Xoo were further characterized by scanning and transmission electron microscopy, Fourier-transform infrared spectroscopy, and X-ray diffraction. Compared with the corresponding chitosan and ZnO alone, CSNPs and ZnONPs showed greater inhibition in the growth of Xoo, which may be mainly attributed to the reduction in biofilm formation and swimming, cell membrane damage, reactive oxygen species production, and apoptosis of bacterial cells. Overall, this study revealed that the two biosynthesized nanoparticles, particularly CSNPs, are a promising alternative to control rice bacterial disease.

Nano-fertilizer(s), an emerging field of agriculture, is alternate option for enhancement of plant growth replacing the synthetic fertilizers. For example, zinc oxide nanoparticles (ZnO NPs) can be used as the zinc source for plants. The present investigation was carried out to assess the role of ZnO NPs in growth promotion of maize plants. ZnO NPs were synthesized using Bacillus sp ., which were characterized using Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM) and X-ray diffraction (XRD). The different concentrations of ZnO NPs ( i . e . 0, 2, 4, 6, 8, 16 mg/L) for growth enhancement of maize ( Zea mays L.) were explored in pot culture experiment. It was observed that size of ZnO NPs ranged between 16 and 20 nm. A significant increase in growth parameters like shoot length (61.7 %), root length (56.9 %) and significantly higher level of protein was observed in the treated plants as compared to control The overall pattern for growth biomarkers including the protein contents was maximum at 8mg/L of ZnO NPs. It was observed that application of biologically synthesized ZnO NPs has improved majority of growth biomarkers including plant growth parameters, protein contents and leaf area. All these parameters were positively influenced by ZnO NPs. Therefore, biosynthesized ZnO NPs could be considered as an alternate source of nutrient in Zn deficient soils for promoting the modern agriculture.

Biosynthesized ZnO NPs (using Bacillus sp) were characterized using Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), X-ray diffraction (XRD) and Zeta potential. Different concentrations of ZnO NPs (2, 4, 8, 16 mg/L) were explored in pot culture experiment. Size of ZnO NPs ranged between 16 and 20 nm.
