The study demonstrates the production of nanomagnesium oxide prepared using the hydrothermal method. As well as studying the optical, morphological and structural properties of magnesium oxide. As well as studying the effect of concentration on inhibiting negative Gram bacteria Escherichia coli (E. coli) activity. According to the structural parameters analyzed with FESEM, all preparations with varying amounts of MgO had an erratic crystal structure. According to the optical properties, changes in material concentration resulted in an increase in the absorption value (2.011, 2.11, 2.25 a.u). energy gaps are determined to be between 1.7-2.03 eV since this intersection represents the energy gap of the permitted direct digital transitions. MgO nanoparticles were agglomerated with irregular morphologies and displayed a spherical perimeter. The MgO nanoparticles that were produced using hydrothermal synthesis have a morphology that is characterized by a particle size of sixty nanometers. A crystalline -structure of a produced MgO NPs was examined. Major powerful peaks with 2θ values of 39.52, 36, 33.72, 33.705, 33.64, 33.63, 32.49, 20.61, 19 and 18.53 degree. A data indicated that an inhibitory effect of MgO nanoparticles is depending on (concentration). A highest concentration of 2 g magnesium oxide was the most inhibitory to Gram-negative bacteria E. coli.
