    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.

    Abstract: An objective of invention is conveniently concentrating a metal in a metal ion-containing solution with high efficiency and to recover the metal from the metal ion-containing solution with high recovery efficiency. A method for concentrating or recovering a metal in a metal ion-containing solution in the present invention is the method comprising the following steps, a reduction and accumulation step to reduce the metal ion into a metal fine particle and also to accumulate the metal fine particle in the microorganism by allowing the microorganism and an electron donor B to act on a metal ion-containing solution W 0 and thus to obtain a solution W 1 that contains a microorganism having a metal fine particle accumulated therein; a concentration step to concentrate the solution W 1 that contains the microorganism having a metal fine particle accumulated therein by a filtration membrane and thus to obtain a concentrated solution W 2 ; and a return step to return the concentrated solution W 2 to first step above and thus to circulate. Further, A device for metal concentration or recovering in the present invention comprises the following: a storage unit 2 to store the solution W 1 , a concentration unit 3 to concentrate the solution W 1 that is transferred from the storage unit 2 by a filtration membrane, and a return unit 4 to return a concentrated solution W 2 that is concentrated in the concentration unit 3 to the storage unit 2.
