In the present study, accumulation and chemical states change of Cs by unicellular fungus of Saccharomyces cerevisiae have been studied to elucidate the role of microorganisms in the migration of radiocesium in the environment. The accumulation experiments of radiocesium was carried out by using the agar medium containing $^{137}$ Cs and a minerals. The order of accumulation of $^{137}$ Cs in the cells was nearly the same as the inverse of distribution coefficient of mineral for $^{137}$ Cs in the medium solution. These results indicate that the fungus accumulates radiocesium by competitively with minerals in the soils.
