Abstract
Epidemics of infectious acute diseases are caused by bacteria that cause various diseases and the increase of antibiotic resistance, which has encouraged drug companies and researchers to search for new antibacterial agents.. the aim of this study, involved the creation, characterization and antibacterial studies of silver nano-particles by using bacterial culture supernatant of bacteria Klebsiella pneumonia the production. We used an eco-friendly extracellular bio-synthetic method for the production of the silver nanoparticles. The biosynthesis SNPs solution were initially categorized by several techniques, the UV-vi. spectrophotometric record absorbance a powerful peak at 432 nm, analysis (FTIR) Fourier Transformer Infrared and (SEM) Scanning Electron Microscope. The SNPs solution showed anti-microbial activity against different types of pathogenic bacteria that used in the present study: Gram negative (Pseudomonas aeruginosa, Escherichia coli), Gram positive: (Staphylococcus aureus, B. cerius).
