In this study, ZnONPs were biosynthesized from aqueous zinc sulphate solution through a simple and ecofriendly method using Pseudomonas aeruginosa culture filtrate, which acted as a reductant and stabilizer simultaneously. ZnONPs were characterized using UV-Vis spectroscopy, XRD, FTIR, SEM, AMF, and zeta-potential analysis.The surface plasmon resonance peaks in absorption spectra for ZnONPs colloidal solution showed an absorption peak at 378 nm in a UV-visible spectrum. The functional biomolecules such as carboxyl groups present in the Pseudomonas aeruginosa culture filtrateresponsible for the zinc oxide nanoparticles formation were characterized by FT-IR. The results of AFM show the tip-corrected measured the size of ZnONPs in the range of 30-80 nm. And the 3D view of the sample surface and height distribution around 50 nm.The XRD results suggested that the crystallization of the bio-organic phase occurs on the surface of the ZnONPs or vice versa. The broadening of peaks in the XRD patterns was attributed to particle size effects and the average particle size of ZnONPs can be calculated using the Debye -Scherrer equation, it was found about 20-40 nm. The ZnONPs were scanned using SEM. It reveals that a ZnONPs seems to be irregular and polymorphic where the crystalline forms of these particles varied between rectangular, spherical, radial and cylindrical structures and the average size ranges between 28-43 nm. Measuring the stability of the colloidal solution of ZnONPs gave a value of -51.8 Mv.The result shows the ability of ZnONPs to inhibit the growth and the biofilms of Pseudomonas aeruginosa isolates.We concluded the biosynthesized ZnO NPs which have antibacterial and antibiofilm activities and it can be used as an antibacterial therapeutic agent.

“…Change in color is the primary test for nanoparticles synthesis shown in Figure (3), color-changing to pale-white is an indication of the formation of ZnO Nanoparticles (Iravani et al, 2011). One of the most important uses of biosynthesis of zinc oxide nanoparticles is that it is cheap, environmentally safe, riskless, easy to operate, and low in toxicity (Heer et al, 2017).…”

The current study involved collecting 225 samples of different age groups and from different clinical sources (burns and wounds). Selective and differential media, Microscopic Examination, Biochemical test, IMVIC tests, and Vitek 2 system were used to identify the bacterial species. The results showed that the bacterial isolates were distributed on Staphylococcus aureus, Pseudomonas aeruginosa, Staphylococcus epidermidis, Klebsiella pneumoniae, Escherichia coli and Proteus mirabilis. All isolates were multidrug-resistant to 12 antibiotics from different classes and according to the susceptibility test, isolate distinction in 2 groups (75 %) of MDR isolates were resistant to (5-9) antibiotics, while (25 %) were susceptible. Zinc Oxide nanoparticles synthesized was done by a green method with Zinc acetate dehydrate as a precursor and aqueous extract of Camellia sinensisas a reducing agent, color-changing to pale-white was an indication of the formation of ZnONPs. The average size and shape of the nanoparticles were detected by using Atomic Force Microscopy (AFM) which was 40 nm with a spherical shape. Scanning Electron Microscopy (SEM) showed the ZnO NPs have spherical, radial, and cylindrical structures. The wavelength range was measured by Ultraviolet-visible spectroscopy (UV-Vis) for monitoring the formation of the nanoparticles, which showed a sharp peak at 325 nm. The average crystallite size of ZnONPs was estimated using Debye Scherrer’s formula were 20-40nm by using X-ray Diffraction (XRD). Fourier-transform infrared spectroscopy (FT-IR) spectra have been used for ZnONPs to detect the functional groups found in the synthesis process via green tea extract. Keyword: ZnO NPs.
