AJWAIN SEEDS AS CAPPING AGENT FOR Bi2O3 NANOFLAKES: SYNTHESIS AND GROWTH INHIBITING EFFICIENCY OF BACTERIA

Objective: This work is mainly focused to determine the antibacterial activity of green synthesized Bi2O3 nanoparticles against bacterial strains, Staphylococcus aureus and Escherichia coli using resazurin as indicator.
 Methods: Bismuth oxide were from precursor bismuth nitrate [Bi (NO3)3.5H20] by trachyspermum ammi (ajwain) seed extract. To carry out these works, NPs undergone characterizations confirmed UV-Vis, FT-IR, XRD, SEM EDAX, TGA-DTA DLS. Biological was done a well diffusion method.
 Results: NP's has been tested bacteria (S. E. coli) in wells shows blue colour, indicating growth inhibition dose-dependent manner for different concentrations.
 Conclusion: The biological studies with one gram-positive gram-negative show inhibiting efficiency. showed good anti-bacterial (different concentrations) S. coli.
