Outline of Final Research Achievements

The research funded by a Scientific Research(C)has led to the publications of two major papers in international journals in open access. Data are available on free online data repository. Numerous scientific communications in international and domestic conferences were given by the PI and co-investigators.
Additional data are going to be published in data report, available online (open access)

Academic Significance and Societal Importance of the Research Achievements

この研究は、鉄と硫黄の循環に新しい洞察をもたらします。 特に鉄の循環は微生物の生命(活動)にとって非常に重要です。 調査されたサイトは、生命の温度限界に近い、高温環境の地下生物圏を対象としていました。
公開された論文は、エネルギーが制限された環境での微生物の活動と、炭素循環(炭素の放出と貯蔵)におけるその役割に関する知識のマイルストーンです。
