Abstract
Biological synthesis of silver nanoparticles (AgNPs) has been an area of research to avoid the harmful effects of the toxic chemicals used in its synthesis on our health and environment. In the present study, a novel strain of Pseudomonas aeruginosa-RTAC 11 isolated from soil was used for the synthesis of AgNPs. Characterization of the synthesized nanoparticles like UV-vis spectroscopy confirmed the synthesis of AgNPs through a signature peak at 420 nm. Fourier Transform Infrared (FTIR) spectroscopic analysis revealed the capping of AgNPs by proteins through signature functional groups. The nano-size of the particles were confirmed using scanning electron microscopy (SEM). The AgNPs showed good antibacterial activity against Escherichia coli ATCC 8739 and Staphylococcus aureus ATCC 6538, thus indicating an excellent antibacterial agent.
