SHORT REPORT

Selenite and Tellurite Reduction by Shewanella oneidensis

Received 1 February 2005/ Accepted 3 April 2005

Shewanella oneidensis MR-1 reduces selenite and tellurite preferentially under anaerobic conditions. The Se(0) and Te(0) deposits are located extracellularly and intracellularly, respectively. This difference in localization and the distinct effect of some inhibitors and electron acceptors on these reduction processes are taken as evidence of two independent pathways.
