摘要

Reduction of selenite (Se(IV)) to the insoluble elemental nontoxic form has been reported to occur by microbial (biotic) activity and in the presence of iron (Fe(II,III)) (abiotic). While Fe is abundantly present in various systems its significance on microbial reduction of Se(IV) has not been studied. We have investigated biotic reduction of Se(IV) int he presence and absence of Fe(II) and Fe(III) by Bacillus and Desulfovibrio isolated from a cyanide heapleach pad. Bacteria were grown on agars supplemented with Se(IV) and Se(IV) with Fe(II)/Fe(III) combinations. Growth of both bacteria species occurred on all supplemented agars at various pH ranges (3.49 < pH < 7.30). Se(IV) was reduced by both bacteria species growing on Se(IV) and Se(IV)Fe(II) agars. Fe(II) and Fe(III) individually and in combination reduced Se(IV) in aqueous solution (abiotic control) demonstrating that reduction of Se(IV) was not limited to either biotic or abiotic processes. Because microbiological reduction of higher valent states of Se can be used to remove Se we suggest monitoring of Se(IV) reduction by microorganisms moderated by Fe species be included in bioremediation systems.
