Title:
A recovery method of the precious metals
Document Type and Number:
Japanese Patent JP6230033
Kind Code:
B2
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.
