Abstract

Potato (Solanum tuberosum L.) is a significant vegetable and one of the most widely consumed crops. Photochemical investigation revealed that the potatoes had antibacterial, anticancer and antioxidant properties. In this study, Basciflik Potato Genotype (BPG) was used for the synthesis of silver nanoparticles. The BPG was extracted with distilled water. After filtration, the solution was treated with silver nitrate at 50°C to yield silver nanoparticles (AgNPs). The color change indicated the formation of AgNPs. Moreover, the structure AgNPs was elucidated by spectroscopic techniques such as Fourier transform infrared spectroscopy (FTIR), Ultraviolet-visible (UV-Vis), X-ray diffraction (XRD), and Scanning electron microscope (SEM). The characteristic functional groups were presented by FTIR. The signal observed at 3267 cm-1 corresponded to the hydroxyl group. The absorption at 430 nm in UV-Vis spectrum showed establishment of AgNPs. The crystalline structure of AgNPs was confirmed by XRD analysis. SEM analysis also revealed the desired product with the average size of 37.31 nm. The antibacterial activity of AgNPs was carried out using Staphylococcus aerus, Salmonella Enteritidis, Escherichia coli, Listeria monocytogenes bacteria. The AgNPs have considerable antibacterial activity at Minimum Inhibition Concentration (MIC), 0.5 mg/mL except for E. coli which revealed the activity at 0.25 mg/mL.
