| Outline of Final Research Achievements |
This study focused on iron-oxidizing bacteria (FeOB) that produce extracellular ferric iron biominerals. For the first time, we reported isolation and cultivation of FeOB growing in brackish water, but not in freshwater nor normal seawater. We also provided novel insights into spatial distribution, diversity, and physiology of freshwater and marine FeOB using culture-dependent and independent analyses. Our results suggest that FeOB and biogenic iron biominerals play a considerable role in elemental cycling in natural environments.
