Outline of Final Research Achievements |
This research aims to investigate the possibility of substance production utilizing carbon dioxide in the seawater independent of photosynthesis, and to construct a circulation system to remove CO2 from the environment using microbial functions. In order to achieve the purpose, it is necessary to establish a new mass-culturing method of chemotrophic bacteria and to evaluate the usefulness of extracellular organic materials they produce. In this study, we succeeded in developing a mass-culturing method of marine iron oxidizing bacteria using CO2 in the seawater as the carbon source for their growth. Moreover, we succeeded in isolating a number of new iron-oxidizing bacteria using this method, as well as in clarifying the composition and structure of extracellular organic materials they produce. Through the present research, we obtained crucial knowledge required for the development of a system to produce organic materials from CO2 in the seawater by microbial activity.
