| Popis: | Silver nanoparticles (AgNPs) have been known for their inhibitory and bactericidal effects in the past decades. Silver Nanoparticles were synthesized by an eco-friendly biogenic approach mediated by using the bacterial culture (SP3). The antibacterial activity of the biogenic Ag nanoparticles was carried out by the conventional Kirby-Bauer well diffusion method against the selected Gram-positive (Staphylococcus aureus, Bacillus cereus) and Gram-negative (Escherichia coli, Vibrio vulnificus) bacterial strains. Silver nanoparticles exhibited maximum antagonistic activity on Vibrio vulnificus (14 mm) and Bacillus cereus (13 mm). The MIC of Ag NPs against Bacillus cereus and Vibrio vulnificus was found to be 200 µg/ml. Larvicidal activity gradually increased with the increase in the concentration of nanoparticles, exhibiting a maximum level (88.33 %) in the presence of 100 µg/ml of Ag NPs. |
