Green Synthesis of Datura stramonium (Asaangira) Leaves Infusion for Antibacterial Activity through Magnesium Oxide (MgO) Nanoparticles

Abstract

The biosynthesized magnesium oxide nanoparticles were pigeon-holed with X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) spectrophotometer, scanning electron microscope (SEM), and photoluminescence spectrometer (PLs) and antibacterial activity. Datura stramonium leaves extract has been used in the present work,; which has medicinal value, and we have synthesized magnesium oxide nanoparticles from both chemical and biosynthesis techniques. The XRD result indicates the realization of crystalline magnesium oxide nanoparticles, and again it is also inveterated with an ultraviolet-visible (UV-Vis) spectrophotometer. The superficial morphology expresses that magnesium oxide nanoparticles have a bulbous morphological shape for both biosynthesis and chemosynthesis. The antibacterial activity of magnesium oxide nanoparticles obtained from Datura stramonium leaves against E. coli and S. aureus was studied. The antibacterial activity also shows a good zone of inhibition. Both techniques are promising for the preparations of MgO nanoparticles in antibacterial activity and show the same result. This outcome demonstrates that the biosynthesized nanoparticles originate from having some medicinal uses and are biodegradable.

Bacteriophage-mediated biosynthesis of MnO2NPs and MgONPs and their role in the protection of plants from bacterial pathogens

“…Recently, the excellent antimicrobial activity of micro-organism bio-inspired MgONPs and MnO 2 NPs on different microbial pathogens were reported ( El-Sayyad et al, 2018 ; Arasu et al, 2019 ; Saka et al, 2022 ). Likewise, the bacterial number of strain GZ 0003 was significantly reduced at all concentrations (50, 100, and 200 μg/mL) when treated with MgONPs and MnO 2 NPs.…”
