| Research Abstract |
The main objective of this study is to reveal the molecular mechanisms of microbiologically induced corrosion (MIC) in the deep-sea environments. During the investigation process, we have succeeded in isolation of a high H2S-producing novel bacterium, chemical analyses and biological studies of the natural corrosion areas (iron mats), as well as establishing a new analytical method for directly determining the relationships between mineral and microorganisms.
