Biosynthesis of silver nanoparticles from the culture supernatant of Bacillus marisflavi and their potential antibacterial activity
چکیده انگلیسی

Silver nanoparticles (AgNPs) were prepared using culture supernatant of Bacillus marisflavi, a novel strain isolated from agricultural wastes. The formation of the AgNPs was confirmed using various analytical techniques such as UV–vis absorption spectroscopy, dynamic light scattering (DLS) and transmission electron microscopy (TEM). The antibacterial effect of synthesized nanoparticles was investigated against Pseudomonas aeruginosa. Furthermore, the mechanism of action of cell death of P. aeruginosa was confirmed by reactive oxygen species (ROS) generation in AgNPs treated cells and also our results clearly indicate that AgNPs could induce generation of ROS by dose dependent manner.
