| Research Abstract |
The aim of this study was to show the applicability of biogenic iron hydroxides produced by acidophilic iron oxidizing bacteria for recovery of rare metals dissolved in water phase. A newly isolated bacterium, strain GJ-E10, was used to prepare the biogenic iron hydroxide minerals schwertmannite and goethite, which were produced independently by controlling the culture conditions. Sorption experiments showed that these biogenic minerals had high sorption capacities for metal ions including molybdate and arsenate and were expected to be useful in recovering these metal ions.
