During the research it was investigated that Sac­charomyces spp. BDU-A1, Saccharomyces spp. BDU-X3, Saccharomyces spp. BDU-Ü4, Saccharomyces spp. BDU-XR1, Saccharomyces spp. BDU-ŞR5 and Saccharo­myces spp. BDU-TR 6 stamms that can change the color of reaction mixture, are also able to produce (actively or passively) silver nanoparticvles. Silver nanoparticles produced by Saccharomyces spp. BDU-A1, Saccharomyces spp. BDU-X3 and Saccharomyces spp. BDU-TR 6 stamms, have showed underUV-VİS spectrophotometer the peak of absorbtion of 405 nm length. Others, produced by Saccharomyces spp. BDU-Ü4, have showed that of 410 nm length; produced by Saccharomyces spp. BDU-ŞR5 - of 425 nm length; by Saccharomyces spp. BDU-XR1 - 415 nm length. İn comparison to other kinds of studied stamms, this particular kind has produced silver nanoparticles havecircle form and size of 17,2 nm. The most active process of biosynthesis of silver nanoparticles took place in Saccharomyces spp. BDU-XR1 stamm.
