Post adsorption of REEs on microorganism

Jiang, M.; Onuki, Toshihiko; Utsunomiya, Satoshi*

Post adsorption of REE by microorganisms has been studied by long-term exposure experiments. In the experiments using Yb, concentration of Yb decreased with increasing time. SEm and TEM analyses showed development of nano-particles including Yb and P on the cells surface. XAFS analysis cralified that Yb was initially adsorbed on the functional groups of cells surface, followed by formation of phosphate mineralization.
