Biological reduction of uranyl by Desulfovibrio desulfurican has been considered as a promising pathway for removing U(VI) from groundwater. In this paper, anaerobic batch tests were conducted to explore the effect of two ubiquitous ferric (hydr) oxides, hematite and goethite, on the bioreduction of U(VI) by D. desulfurican. When hematite or goethite (containing solidoid Fe(III) ranging from 10 to 30 mmol/L) was coexistent, U(VI) bioreduction could always be inhibited and the inhibitory effect was increased with increasing content of ferric (hydr) oxide. In the presence of a mixture of hematit...
