Xenorhabdus stockiae KT835471-mediated feasible biosynthesis of metal nanoparticles for their antibacterial and cytotoxic activities

Artif Cells Nanomed Biotechnol. 2017 Dec;45(8):1675-1684. doi: 10.1080/21691401.2017.1282495. Epub 2017 Jan 31.

Abstract

In this study, extracellular metabolites of symbiotic bacteria Xenorhabdus stockiae (KT835471) was employed for the synthesis of silver (XsAgNPs) and gold nanoparticles (XsAuNPs). Synthesized NPs were characterized using high throughput instrumentation which confirms the generation of stable, crystalline XsAgNPs and XsAuNPs with the mean size of 14 ± 6 and 14 ± 5, respectively. Further, the NPs exhibits an excellent bactericidal effect against six different pathogens. On the other hand, NPs displayed an outstanding anticancer activity against human lung adenocarcinoma epithelial cells (A549). Therefore, the present study strongly suggests that metal NPs encrusted with functional bio-moieties can be used for different biomedical applications.
