| Outline of Final Research Achievements |
In the present study, we analyzed in detail the whole genome information of the bacterial symbiont TC1 living in Trimyema ciliate, which plays a major role in a sewage treatment process. As the results, it was shown that TC1 may have obtained amino acids from host ciliate and actively synthesized lipids. In addition, it was revealed that another ciliate closely related to the genus Cyclidium also have symbiotic bacteria of unknown function in addition to methanogens, which was named Hydrogenosomobacter endosymbioticus. Histochemical analysis showed that both methanogens and Hydrogenosomobacter symbiont are in close contact with hydrogen-generating organelle, hydrogenosomes.
