Research Abstract |
To develop the microbial purification and recovery system for rare metal, we explored novel metal metabolizing bacteria from cold environments, such as grass area in Inner Mongolia, China, and glacier area in Austria, and analyzed metal respiration mechanism of a metal-reducing bacterium, Shewanella livingstonensis Ac10. We successfully obtained various cold-adapted stains, and application of these strains is expected to develop the soil purification and rare metal-recovery system at cold environments. We also identified that S. livingstonensis Ac10, a cold-adapted metal-reducing bacterium, inducibly synthesized a specific channel proteins in the presence of trivalent iron, which is involved in iron transport during its iron respiration.
