연구 주제

Chemolithotrophic microorganisms (bacteria and archaea) are widespread among extreme environments such as high temperature (>55 ° C), 낮은 pH (< 3) and high salinity. Acidic environments may occur naturally in geothermal areas, or arise due to human activities (especially metals and coal mining). The iron- and 강원 랜드 슬롯 머신 종류 bacteria play a key role as primary producers in the acidic environments. Also, they are important for biomining owing to their ability to produce ferric iron and sulfate. One of our research topic aims to clarify the dissimilatory oxidation of reduced inorganic sulfur compounds (RISCs) in these bacteria. They have unique enzymes to oxidize RISCs. These enzymes (and sometimes whole cells) are interesting not only scientific aspects but also industrial applications. Tetrathionate hydrolase (4THase) is one of the "unique" proteins involving in the RISCs oxidation in acidophilic iron- and 강원 랜드 슬롯 머신 종류 bacterium Acidithiobacillus ferrooxidans. We have identified the gene encoding the enzyme for the first time and successfully obtained the recombinant 4THase as an active form. We investigate the 3D structure, reaction mechanism, the gene expression, and the regulations. Another RISCs oxidation enzymes such as thiosulfate dehydrogenase are also investigated from marine acidophiles and moderate thermophilic 강원 랜드 슬롯 머신 종류 bacteria as well as A. ferrooxidans. We are interested in microbial communities in acidic environments such as acid mine drainage (AMD). Yanahara pyrite mine is located in North-East Okayama prefecture. We investigate the microbial communities in the AMD from Yanahara mine. Many acidophilic iron- or sulfur- (or both) oxidizing microorganisms were detected by DGGE and RFLP analyses. These bacteria could be used for AMD treatment to avoid environmental damage.
