In our presented work we have studied the effect of various environmental factors on the synthesis of silver nanoparticles by Saccharomyces ellipsoideus BSU-XR1. Silver nanoparticles were formed by growing the yeast in broth medium at 30oC. Filters were used to seperate biomass from broth. Biomass was washed 3 times with 0.1L of distilled water (DW). 10 grams of wet biomass was poured to beaker containing 90 ml of sterile DW. 1 ml of 10-3 molar solution of Silver nitrate was poured to it, and this mixture with silver nitrate salt was incubated in a dark environment. It was determined that, the optimal condition for the production of silver nanoparticles was being on the 21st day of incubation, in 10 grams of wet biomass. For the cultivation of the studied yeast strain, the synthesis of silver nanoparticles took place in the range of 25-30°C. Tthe initial pH of the medium was 7.0. and the concentration of silver nitrate was used as salt at conntration of 0.5 mM and 1.0 mM. The optimal conditions of incubation were in dark environment in all variotions of experiments.

“…Resulted nanoparticles were smaller in size, uniform, monodispersed in nature, and were synthesized very rapidly.The presented research work explored that due to silver nanoparticles possess excellent physical and chemical properties, they will have great potensials in medical and biological applications. An efficient and simple biosynthesis method to produce silver nanoparticles has been developed by incubating yeast cells with AgNO 3 . Further studies are required on understanding the cellular and molecular mechanism of AgNPs formation.…”

“…Obtaining of nanoparticles by physical and chemical methods is not considered ecofriendly [2]. The majority of the technical processes used in this case can be caused by environmental pollution, which occur with the use of chemical reagents From this point of view, greater attention is paid to the synthesis of nanoparticles through biological objects [3,4]. The biological method of nanoparticle synthesis is a relatively simple, cheap, and environmentally friendly method [5].…”

Presented work was dedicated to synthesis of silver nanoparticles by yeast strain Candida macedoniensis BDU-MI44, which was procured from the culture collection of the Department of Microbiology. It was founded that this yeast strain is capable of forming silver nanoparticles. First of all its ability to form silver nanoparticles were detected by to stain reaction medium in a dark color and by to give absorption wavelength of 405 nm in UV-spectrophotometer.In the electron microscope the nanoparticles are observed with a spherical shape and its sizes are 14 -23 nm. According to the characteristic X-ray spectrum specified that these nanoparticles are silver.

In the presented work, the literature data on the influence of various environmental factors were analyzed on the formation of silver nanoparticles by yeast strains. It was determined that the optimal conditions for the synthesis of silver nanoparticles by the yeast strain Saccharomyces ellipsoideus BSU-XR1 were on the 21st day of incubation, on 4-6 days of incubation in different strains of Saccharomyces cerevisiae, and between 2-10 days in Candida strains. The optimal amount of wet biomass was between 8 and 10 g for Candida strains and 10 g for Saccharomyces strains. The temperature limit for Saccharomyces was observed at 25-35°C, and for Candida at 25-37°C. For strains, synthesis of silver nanoparticles was optimal in the pH range of 4-10, and pH range of 7 for Candida strains. Depending on the concentration of AgN03 salt, the optimal synthesis of silver nanoparticles occurred at concentrations of 0.5 and 1 mM for Saccharomyces, and 1 mM for Candida. The optimal incubation conditions for both sexes were under dark environment.
