Currently, the biosynthesis of silver-based nanomaterials attracts enormous
attention owing to the documented antimicrobial properties of these ones. This
study reports the extracellular biosynthesis of silver nanoparticles (Ag-NPs)
using a Pseudomonas aeruginosa strain from a reference culture collection. A
greenish culture supernatant of P. aeruginosa incubated at 37°C with a silver
nitrate solution for 24?h changed to a yellowish brown color, indicating the
formation of Ag-NPs, which was confirmed by UV-vis spectroscopy, transmission
electron microscopy, and X-ray diffraction. TEM analysis showed spherical and
pseudospherical nanoparticles with a distributed size mainly between 25 and
45?nm, and the XRD pattern revealed the crystalline nature of Ag-NPs. Also it
provides an evaluation of the antimicrobial activity of the biosynthesized Ag-NPs
against human pathogenic and opportunistic microorganisms, namely, Staphylococcus
aureus, Staphylococcus epidermidis, Enterococcus faecalis, Proteus mirabilis,
Acinetobacter baumannii, Escherichia coli, P. aeruginosa, and Klebsiella
pneumonia. Ag-NPs were found to be bioactive at picomolar concentration levels
showing bactericidal effects against both Gram-positive and Gram-negative
bacterial strains. This work demonstrates the first helpful use of biosynthesized
Ag-NPs as broad spectrum bactericidal agents for clinical strains of pathogenic
multidrug-resistant bacteria such as methicillin-resistant S. aureus, A.
baumannii, and E. coli. In addition, these Ag-NPs showed negligible cytotoxic
effect in human neutrophils suggesting low toxicity to the host.
