| Research Abstract |
The aim of this study was to develop a microbial enrichment culture that produces biogenic ferromanganese oxides and to show the applicability of the microbial culture to purification of groundwater contaminated with trace metal ions. The biogenic oxides showed a high ability for sorption of dissolved trace metals such as Zn^<2+>. It was suggested that an unknown group of α-Proteobacteria played a major role in the Mn oxide production. Further analysis of such bacteria would lead to the development of effective bioprocesses for purification of contaminated groundwater.
