As a result of the research, the ability of Saccharomyces ellipsoideus BDU – XR1 yeast fungus to synthesise silver nanoparticles was observed both in change of color of reaction mixture in a light and dark environment, and during the spectrophotometric analysis. During the UV – Vis spectrophotometric analysis, incubation in the dark environment showed 414 nm length peak. Incubation in the light environment showed 409 nm length peak. While observed under the scanning electron microscope, there were distinguished 17,2 nm spheric silver nanoparticles in the sample incubated in dark environment. The dark environment is the most optimal one for this strain.
