Abstract

   This study aims to  biosynthesis of gold nanoparticle (AuNPs) by  using Bacillus subtitles supernatants under ambient condition with  optical diagnose wine red color.(AuNPs) characterization using UV-spectroscopy, X-ray diffraction(XRD), Field Emission Scanning Electron Microscope (FE-SEM) techniques. Evaluation of the antibacterial activity of AuNPs against four pathogenic isolates collection from different clinical sources, three Gram-negative are Pseudomonas aeurginosa, Proteus mirbilis, Enterobacter cloaca and one Gram-positive isolate is Staphlococcus haemolytic. The results showed effective inhibitory activity using gold nanoparticle (AuNPs).It can be used as a alternative drug to commercial antibiotics.
