Zinc oxide, an established inorganic metal oxide in nanoparticles form exhibits tremendous anti-bacterial activity. The present study focuses on determining the anti-bacterial activity of green synthesized zinc oxide nanoparticles (ZnO NPs). Results clearly validate the effective synthesis of spherical shaped nanoparticles with average size range of 60–80 nm. SEM and EDAX data buttresses the results obtained by XRD pattern in terms of size and purity. ZnO NPs exhibited dose-dependent anti-bacterial activity against Escherichia coli (E. coli) and the IC50 value was calculated to be around 20 μg/mL. Growth kinetics study was conducted in the presence of nanoparticles which demonstrated the bacteriostatic effect of ZnO NPs. The study recommends the potential use of ZnO NPs in industries like food, pharmaceutical, agriculture, cosmetic industries for its anti-bacterial activity. © 2019 The Authors
