Abstract
Silver nanoparticles (AgNPs) used in this study were prepared from Ziziphus jujuba Mill. aqueous pericarp extract. Potent antibacterial activity was recorded from AgNPs-Z. jujuba pericarp against P. Pseudomonas aeruginosa > K. Klebsiella pneumoniae > M. Micrococcus luteus > S. Staphylococcus aureus > P. Proteus mirabilis > S. Shigella flexneri. Less antifungal activity was found against phytopathogenic fungi with inhibition efficacy of P. Penicillium expansum > M. Macrophomina phaseolina > A. Alternaria alternata > D. Drechslera halodes, F. Fusarium oxysporum f. sp. lycopersici. UV-Vis spectral analysis of formed AgNPs- Z. jujuba was recorded at 450 nm and three characteristic diffraction peaks observed at 2 theta =38.235, 43.95 and 64.42. FTIR patterns were located in the region of 4000-400 cm-1 and AgNPs particle size were noticed in between 20 and 71 nm with spherical shape embedded in bio-materials. These findings indicate that AgNPs-Z. jujuba pericarp aqueous extract could be utilized to control various bacterial infections to human and as well as against phytopathogenic fungi.
