Antimicrobial efficiency of biologically synthesized nanoparticles using root extract of Plumbago zeylanica as bio-fertilizer application

H. Patel*and R. Krishnamurthy


The synthesis of nanoparticles using biological system is in wide research due to the potential applications in Nano medicines. The biological synthesis of nano-particles is less expensive & eco-friendly. In the present study, the silver nanoparticles are synthesized rapidly due to the root extract of medicinal plant Plumbago zeylanica. After assessing the formation of silver nanoparticles, these phyto-synthesized silver nanoparticles were tested for their antibacterial activity against test cultures of Bacillus cereus, Straptococcus aureus, Serratia marcescens and Escherchia coli. The antibacterial property of silver nanoparticles was analyzed by measuring Zone of Inhibition.  The silver nanoparticles synthesized from root extract of Plumbago zeylanica showed toxic effect on Bacillus cereus, Straptococcus aureus, Serratia marcescens and Escherchia coli. The outcome of this study will help in future to develop value added drug from medicinal plant for biomedical and nanotechnology based industries.
