Selenate reduction to elemental selenium by anaerobic bacteria in sediments and culture: Biogeochemical significance of a novel, sulfate-independent respiration
Ronald S. Oremland, James T. Hollibaugh, Ann S. Maest, Theresa S. Presser, Laurence G. Miller, Charles W. Culbertson
1989, Applied and Environmental Microbiology (55) 2333-2343
Interstitial water profiles of SeO42−, SeO32−, SO42−, and Cl− in anoxic sediments indicated removal of the seleno-oxyanions by a near-surface process unrelated to sulfate reduction. In sediment slurry experiments, a complete reductive removal of SeO42− occurred under anaerobic conditions, was more rapid with H2 or acetate, and was inhibited by O2, NO3−, MnO2,...
