Extracellular, biosynthesis of silver nanoparticles using Enterobacter cloacae (mk163462) and their antibacterial activity against certain multidrug resistant pathogens

Abstract

In the present investigation, the extracellular biosynthesis of silver nanoparticles using the culture filtrate of silver resistance isolate Enterobacter cloacae (MK163462) was reported. The biosynthesized silver nanoparticles were characterized by UV-Visible spectrophotometer, FT-IR, SEM and XRD analysis. The AgNPs were spherical, with a size ranged from 12 to 30 nm. Antibacterial activity and synergistic potential of synthesized silver nanoparticles were assessed against certain MDR strains. The silver nanoparticles alone and combination with antibiotics showed greater antibacterial activity against all the MDR strains used in the present study.
