Biogenic Silver Nanoparticles Produced by Bacteria Isolated from University Campus Environment Soil Samples in Ras Al Khaimah

Silver is observed to be comprised of a huge percentage of silver oxide and the utilization of silver and silver salts is in practice since ancient human civilization. Silver nanoparticles remain to be potential antifungal, antibacterial, anti-inflammatory, and antiviral agents. Further, it is demonstrated that silver nanoparticles have been involved in arresting the growth of several bacterial species thereby reducing their harmful effects. Micro-organisms are being utilized as eco-friendly nano-factories for the synthesis and bio-production of various nano-meter-sized compounds. Metals and micro-organisms are collaborative. Concurrently, micro-organisms are also capable of extracting or accumulating metals. The study suggested an eco-friendly approach for the extracellular synthesis of AgNP using soil-derived actinomyces followed by tracing its efficacy against bacteria. The characteristic of AgNP is the UV-Visible with also the FTIR method. Synthesized nanoparticles are screened for Streptomyces antibacterial activity by cross streak method followed by PCR analysis. The particle size distribution per intensity is estimated by the Dynamic Light scattering method. The study also predicted that the hydrodynamic diameter of the particles increases with the increase in the repetition rate. The microbial synthesized AgNP has been observed to possess high toxicity to bacteria with a greater antimicrobial property. © 2022 Pooja Shivappa, Grisilda Vidya Bernhardt, Sheela Haridas and Michael V Magaogao.
