Evaluation of the Biological Activity of Saccharomyces Boulardii in the Synthesis of Silver Nanoparticles

Abstract

The intention of this study was to determine the efficacy of Saccharomyces boulardii as a biological catalyst.to generate silver ‎ nanoparticles using silver nitrate. Diffraction of X-rays (XRD) .The atomic force microscope (AFM) was employed to investigate the surface traits of the produced silver nanoparticles. According to the conclusions, silver nanoparticles with a standard crystalline size of 14.25 nm, as determined by x-ray spectroscopy (xrd), may potentially be manufactured. The Standard X-ray diffraction (XRD) chart for silver nanoparticles (JCPDS silver: 04-0783) revealed four diffraction values at the two values: 38.6, 44.2, 64.2, and 77.3, which equate to 111, 200, 220, and 311 respectively. Additionally, the silver nitrate solution's color changed to brown with constant shaking after being added to a solution of suspended S. boulardii, which proved that nanoparticles were formed. The appearance of these peaks between the specific wavelength of silver nanoparticles, which ranges between 200 and 800 nm, indicates the presence of nanoparticles. The results of the UV/Vis Spectrophotometer revealed the emergence of three peak levels of absorption at 234, 355, and 488 nm in wavelength. The outcomes also showed that silver nanoparticles' surface topography by atomic force microscopy has a mean diameter of 49.61 nm.
