| Outline of Final Research Achievements |
In this study, we focused on anaerobic acetate oxidizers involved in the reduction of crystalline iron(III) oxides and successfully obtained their enrichment cultures from deep subseafloor core sediments. High-throughput sequencing of 16S rRNA genes revealed that iron reducers affiliated within the phylum Firmicutes may play a pivotal role in the carbon and energy cycles in the deep biosphere. Further, in order to investigate the ecophysiological features of the iron reducers, we established the ultra-high-sensitivity stable isotope probing of 16S rRNA.
