"Biochemical and morphologic characterization confirm the identification. The isolate reduces selenate and selenite to Se-0 under microaerophilic and denitrifying conditions but not under aerobic conditions. It does not use selenate or selenite as terminal e(-) donors. Se oxyanion reduction causes the formation of Se...
