Research Abstract	Dye-sensitized solar cell (DSC) is the next generation of solar cells that combines low manufacturing cost and high efficiency. One of the important factors for obtaining a high power conversion efficiency in the DSC is the dye, and structural analogs of the ruthenium organometallic complex dye indicates a high functionality. In this study, we aimed at improving functionality of the ruthenium dye by modifying with microbial enzymes, which show the various catalytic actions. As the results of the this study, many microorganisms assimilate ruthenium dye were obtained. Furthermore, it is found some ruthenium dye utilizing bacteria metabolized ruthenium dye after adsorbing it. The result was to be expected the discovery of novel ruthenium dye-converting enzyme.
