| Outline of Final Research Achievements |
There is a possibility of constructing an innovative carbon dioxide conversion system different from other autotrophic organisms by utilizing the ability of metal corroding microorganisms that acquire electrons from solid metal and grow with fixing carbon dioxide. In this study, we isolated a novel corrosive microorganism which has acetate producing ability from the environment and identified acetogenic strains showing corrosive ability from acetogens deposited in type culture collection. Genes involved in electron acquisition from solid iron were estimated by transcriptomic analysis when solid iron was used as an electron donor for corrosive acetogen, Clostridium carboxidivorans. In the future, these information obtained in this study might be contribute to construct a novel carbon dioxide conversion system using iron as an electron source and to improve its efficiency.
