Abstract: The present application provides a method to recover noble metal ions by reduction with using yeast. In the method, a liquid containing noble metal ions is provided. An electron donor and yeast are added into the liquid to bring the yeast in contact with the noble metal ions to reduce the noble metal ions. The noble metal can be accumulated in a fungus body of the yeast. The electron donor can be an organic acid, a salt thereof, an alcohol and hydrogen gas.

Abstract: [Problem] To provide a means of using a yeast to recover noble metal ions in reduced form, i.e., as noble metals.[Solution] In a liquid to which an electron donor has preferably been added, Saccharomyces cerevisiae, Zygosaccharomyces rouxii, Schizosaccharomyces pombe or a yeast of the Debaryomyces genus deposited as NITE-BP01780 is brought into contact with metal ions of a noble metal such as gold, palladium and platinum, and the noble metals, being the reduced form of the noble metal ions, are recovered from the recovered yeast.
