In this study, gold nanoparticles (GNPs) were synthesized using an aqueous extract of Fagonia, as a stabilizing and reducing agent, applying the green approach. This study reports an efficient, rapid synthesis of stable AgNPs by a new Pseudomonas strain with high antimicrobial activity. A comparative study between the chemically synthesized and Pseudomonas AgNPs revealed a higher antibacterial activity of the latter against common nosocomial pathogen microorganisms, including Escherichia coli, Staphylococcus aureus and Candida albicans. X-ray diffraction (XRD) revealed a face-centred cubic (fcc) diffraction spectrum with a crystalline nature. Fourier transform infrared (FTIR) spectroscopy found the presence of a high amount of AgNP-stabilizing proteins and other secondary metabolites. Energy dispersive X-ray spectroscopy (EDS) showed the presence of a high intensity absorption peak at 3 keV, a distinctive property of nanocrystalline silver products. The average size was approximately 50 nm. Scanning electron (SEM) and transmission electron microscopy (TEM) revealed spherical polydispersed AgNPs in the size range of 20–70 nm. After incubation of Pseudomonas cultures with 1 mM of AgNO3 at 22 ☌, we obtained AgNPs within 24 h. In this study, for AgNP biosynthesis, we used a new Pseudomonas strain isolated from a consortium associated with the Antarctic marine ciliate Euplotes focardii. The synthesis of silver nanoparticles (AgNPs) by microorganisms recently gained a greater interest due to its potential to produce them in various sizes and morphologies. Conferring results, present reports that the biological synthesis method was found highly beneficial in fabrication nanoparticles in medicinal applications. Anti-cancer activity of AgNPs revealed potential efficacy against MCF-7 cell lines with 24 h IC50 value of 25 mg/mL. AgNPs showed good anti-inflammatory potential. XRD disclosed crystalline nature of AgNPs with crystalline size of 15.17 nm and Zeta potential at -30 mV indicates good stability. TEM and FESEM analysis reveal nanoparticles are spherical in shape and EDS confirmed presence of elemental signature of silver at 3 KeV. FT-IR studies affirmed presence of phytoconstituents that supports role of metabolites as a reducing and capping agent. UV-visible spectroscopy revealed characteristic absorption maxima at 434 nm. The present study aims to synthesize AgNPs using Caesalpinia bonducella leaf extract by employing a green chemistry approach and was characterized. Plant intervened synthesis of nanoparticles has attracted an ample amount of attention because this method is facile, cost-efficient, and eco-friendly. They were found effective against different clinical isolates of bacteria. cretica extract were spherical and aggregated. It was concluded that the AgNP prepared from F. The antibacterial activity of AgNP (50 µg) was compared with ciprofloxacin (10 µg) and negative controls producing a larger inhibitory zone than the negative and positive controls in a concentration-dependent manner. Significant antibacterial activities against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, and Salmonella enterica were observed. Different functional groups were detected in AgNP by Fourier transform infrared spectroscopy. The AgNP were crystalline, spherical in shape ranging in size from 20 to 50 nm, and clustered. The AgNP were morphologically characterized using different techniques and their antibacterial activity was also evaluated. The present study was designed to prepare the silver nanoparticles (AgNP) from F. is a known medicinal plant containing important biomolecules.
