Outline of Final Research Achievements

This study confirmed that the unicellular alga, Pseudococcomyxa simplex and Chlamydomonas reinhardtii, accumulated high concentrations of Au, Pd, Ag, and Pt. The chemical forms of Au and Pd accumulated by these algae were clarified by X-ray absorption fine structure (XAFS) analysis. This study was also the first to successfully visualize the distribution of Au and Pd in a unicellular alga by X-ray fluorescence (micro-XRF) imaging.
