| The aim of this study was to study the antibacterial activity of Silver nanoparticles synthesized by L. acidophilus and the biosynthesis of AgNPs from nonpathogenic bacterial isolates. Fifty samples were obtained during the period from December 2020 to March 2021. AgNO3 was used as a precursor for the synthesis of AgNPs. Biological AgNPs were originally shown by change the color, yellow to reddish-brown. The categorization of AgNPs accomplished by SEM, XRD, AFM, and EDS. SEM exhibited well-dispersed AgNPs, homogenous with a diameter of 40-60 nm, with inconstant shapes, mostly spherical form. XRD detected that the size of AgNPs was 34 nm. AFM also showed the three-dimensional structure of AgNPs and their diameter which was 45.82 nm. EDS exhibited that the AgNPs fabricated was 94.82% silver and 5.18 % oxygen. Silver nanoparticles displayed antibacterial action to MDR of P. mirabilis. | ||
