dc.description.abstractThis study aims to prepare silver nanoparticles (AgNPs) and investigate its effects on the growth of some pathogenic bacteria affecting potato crops. The green synthesis of AgNPs, from silver nitrate using marine algae as a novel bioresource of cost-effective nonhazardous reducing and stabilizing compounds. Biosynthesis of AgNPswill be indicated by the change in mixtures color from light yellow to brown. The resulting AgNPswill be characterized by UV-Vis spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), and atomic force microscopy (AFM). The possible functional groups of phytochemicals or proteins in Algae that help in the reduction of Silver nitrate to AgNPs and its stabilizations will be determined using Fourier Transform Infrared spectroscopy (FTIR). The antibacterial activity of synthesized AgNPs against Erwiniacartovorawas investigated.en_US

dc.description.conclusionsThe best concentration of silver nitrate as a reductant to red algae extract was 1 mM; which gave the ideal results for AgNPs characterization. Finally, this study showed that silver nanoparticles revealed good antibacterial activities against gram-negative bacteria isolated from potato samples. We learned that the microorganisms are unlikely to develop resistance against AgNPs as compared to antibiotics, because silver attacks a wide range of targets in the cell of microorganisms. However, this work is following previous researches that hope to witness in the coming future the integration between nanotechnology and bacteriology leading to possible advances in the formulation of new types of bactericides and a good recovery and treatment agents of wastewater from many organic dyesen_US
