The Biosynthesis of Silver Nanoparticles by Moringa Oleifera and its Antibacterial Activity

The study was amid to synthesized and characterization of silver Nanoparticles (AgNPs) from Moringa oleifera (M. oleifera) leaves and seeds extract, and to investigate the antibacterial activity against gram-positive (Staph.aureus and Enterococcus feacalis) and gram-negative (Pseudomonas aeruginosa, Acinetobacter lwoffii, Shigella spp, Citrobactor spp, Alcaligenes spp. and E.coli). The synthesized nanoparticles was characterized by UV-visible and Fourier transform infrared (FTIR) spectroscopy. The result of UV-visible reveals broadband absorption for both leaf and seed extract. The FTIR analysis showed that AgNPs contains the functional groups. The antibacterial activities against mentioned pathogens were done by using agar well diffusion method, the considerable inhibitory action for both leaf and seed extract were observed both in gram-positive and gram-negative bacterial isolates.
