Biosynthesis of MgO Nanoparticles Using Klebsiella pneumoniae and Staphylococcus aureus

Abstract

The current study describes a low-cost, environmentally friendly, and repeatable magnesium oxide nanoparticle manufacturing process mediated by Klebsiella pneumoniae and Staphylococcus aureus. The purpose of this study was to produce magnesium oxide nanoparticles by employing the bacterial culture supernatant of (Klebsiella pneumoniae and Staphylococcus aureus)  and to characterize them.The magnesium oxide nanoparticles were created using an environmentally acceptable extracellular bio-synthetic technique.magnesium nitrate were used as a source of MgO NPs. Ultraviolet-visible (UV-Vis), X-ray diffraction (XRD), Energy dispersive X-ray (EDX), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) were used to analyze the MgO NPs. The XRD pattern showed fifth major peaks of the crystalline metallic MgO NPs. The UV spectrum of the MgO K.pneumoniae NPs showed a sharp absorption peak at 330 nm and 334 nm for MgO S.aureus NPs. According to the current study's findings, K.pneumoniae and S.aureus bacteria are both capable of creating MgO NPs extracellularly.
