Effect of Phyto‐Assisted Synthesis of Magnesium Oxide Nanoparticles (MgO‐NPs) on Bacteria and the Root‐Knot Nematode

Abstract

The root-knot nematode was examined using magnesium oxide nanoparticles (MgO-NPs) made from strawberries. The biologically synthesized MgO-NPs were characterized by UV, SEM, FTIR, EDS, TEM, and dynamic light scattering (DLS). Nanoparticles (NPs) were examined using scanning electron microscopy (SEM) and transmission electron microscopy (TEM) and shown to be spherical to hexagonal nanoparticles with an average size of 100 nm. MgO-NPs were tested on the root-knot nematode M. incognita (Meloidogynidae) and the plant pathogenic bacteria Ralstonia solanacearum. The synthesized MgO-NPs showed a significant inhibition of R. solanacearum and the root-knot nematode. MgO-NPs cause mortality and inhibit egg hatching of second-stage juveniles (J2) of M. incognita under the in vitro assay. This study aims to examine the biological activity of biogenic MgO-NPs. The findings marked that MgO-NPs may be utilized to manage R. solanacearum and M. incognita and develop effective nematicides. In addition, the antioxidant capacity of MgO-NPs was determined by using 2, 2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH).

Establishment of the Most Effective Methods of Obtaining Nanosize Magnesium Oxide

“…Data obtained by the researchers and the frequency of formation of classes of magnesium oxide nanoparticles by size characteristic were confirmed by J. Chen [25]. However, one of the main features of MgO nanoparticles (NPs) is its high antibacterial activity, which is confirmed by numerous studies, among which the papers by A. Khan et al [27], J. Maji et al [28], N. Baniasadi et al [29], B. Das et al [30], L. Cai et al [31]. However, this property is more clearly confirmed and illustrated in the study by N. Y. Nguyen et al [32].…”

“…Moreover, expanding the range of the research vector with the papers by A. Khan et al [27], J. Maji et al [28], N. Baniasadi et al [29], B. Das et al [30], L. Cai et al [31] and, in particular, N.Y. Nguyen et al [32] allowed creating a more complete picture of the properties of the target nanostructure, forming cross-branch bonds and transitions for the latter (due to the detected antibacterial activity). The applied approach established the median physicochemical and specific properties of the nanostructure under study, which allows creating appropriate verification information array of values that can be referenced when applying subsequent iterations in the current study.…”

“…Furthermore, the diameter obtained by DLS analysis may be influenced by the uneven distribution of NPs in the colloidal dispersion and the presence of coating agents from the plant extract around the NPs, introducing potential interference during size calculations [46]. Similarly, the size of MgO-NPs synthesized by using an aqueous extract of strawberry was 100 nm, according to TEM analysis, and increased to 119 nm based on DLS [47].…”

“…The properties of bitumen depend on the colloidal particles and their stability over time. In order to create this stability and adapt the main indicators of bitumen to the requirements of the standard, it should be modified with bitumen-polymer waste [1][2][3][4][5].…”
