Factors affecting chromium(VI) reduction by Thiobacillus ferrooxidans
(Elsevier Science Sa, 2001-02)
The ability of Thiobacillus ferrooxidans cultures to reduce chromium(VI) to chromium(III) was evaluated under different conditions. In T. ferrooxidans cultures with sulphur as energy source, the capacity for chromium(VI) ...
