ABSTRACT:
A chromium-resistant strain of Shewanella alga BrY and method of using such for removing chromium (VI) from a chromium-contaminated waste stream involving treating the waste stream with the chromium-resistant strain under anaerobic conditions whereby Cr(VI) in the waste stream is reduced, the chromium generally forming a precipitate which can be separated from the waste stream.
