Antibacterial Activity of Biogenic Platinum Nanoparticles: An In vitro Study

Abstract

The aim of this study was to screen the antibacterial activity of biogenic platinium nanoparticles. During this study platinum nanoparticles prepared from marine actinobacteria (Streptomyces sp.) were used to access antibacterial activity against Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae, Proteus vulgaris, Staphylococcus aureus, coagulase negative Staphylococcus sp. and Pseudomonas aeruginosa. During this study, biogenic platinium nanoparticles exhibited broad spectrum antibacterial activity against coagulase negative Staphylococcus sp. (20.33±1.52), followed by Proteus vulgaris (17.66±2.08), Staphylococcus aureus (16.33±1.52), E. cloacae (14.00±2.64) and E. coli (12.33±1.52), while poor antibacterial activity against P. aeruginosa (08.33±0.57) and K. pneumoniae (07.66±1.52).
