Research Abstract

In this study, I formed the working hypothesis of existence of 'Environmental Electric Ecosystem', in which some microorganisms use electric current produced by remote oxidation-reduction reactions in the environment. The purpose of the study was solution of the amount and mechanism of the Environmental Electric Ecosystem.
Through the study subject, we showed that environmental electric current occurred around the deep-sea hydrothermal vents, by analyses of mineral electrical property, mineral catalytic characterization, oxidation-reduction potential in hydrothermal fluid and seawater, and on-site power generation examination, etc. Furthermore, we also showed that microbes adheres to the mineral surface under this environmental electric current. We were not able to realize the long-term microbial cultivation under the deep-sea electrical current because of bad weather. However, future progress is promising about the enrichment cultivation of the current use microbes in the laboratory.
