| Outline of Final Research Achievements |
During the research period, analytical method was developed to quantify coenzyme F430 from various environmental samples. The sensitivity of the developed method is 100000 times higher than the conventional method, which can quantify coenzyme F430 at 0.1 femto mol. The mothod made it possible to quantify coenzyme F430 from marine sediments, microbial mats, paddy soils, groundwater etc. Coenzyme F430 was detected coalbeds located at 2000 m below seafloor offshore Shimokita Peninsula (world record of deep biosphere), suggested presence of active methanogens. This study was published from Science.
The scientific results was published from totally 4 peer reviewed scientific journals and presented at 11 conferences and received high international evaluation.
