High potential application in bioremediation of selenate by Proteus hauseri strain QW4.

Abstract

The concentration of toxic sodium selenate (1000 μg/ml) in the supernatant of the bacterial culture medium decreased by 100% after 2 days and the color of the medium changed to red due to the formation of less toxic elemental selenium. Also, our results imply that heavy metal pollution may contribute to increased antibiotic resistance through indirect selection.
