Abstract
The aim of the present study was to investigate the in-vitro antimicrobial activity of zinc nanoparticles synthesized from ethanol extract of Momordica charantia fruit. Antimicrobial activity was evaluated for Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus and Aspergillus flavus by using disc diffusion method. The result obtained showed that the zinc nanoparticles had a potent antimicrobial activity against all the bacterial species. However no growth inhibitory activity was observed against Aspergillus flavus.
Keywords: Bitter gourd extracts, antimicrobial activity, zinc nanoparticles, Disc diffusion method, E. coli, S. aureus, A. flavus.
