Journal ArticleDOI
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 +5 more
TL;DR: Results indicate that dissimilatory selenate reduction to elemental selenium is the major sink for selenia oxyanions in anoxic sediments and suggest application as a treatment process for removing selenio-oxyanions from wastewaters and also offer an explanation for the presence of selenite in oxic waters.
Journal ArticleDOI
Methylmercury decomposition in sediments and bacterial cultures: involvement of methanogens and sulfate reducers in oxidative demethylation.
TL;DR: The results indicate that both aerobes and anaerobes demethylate mercury in sediments, but that either group may dominate in a particular sediment type.
Journal ArticleDOI
Isolation, Growth, and Metabolism of an Obligately Anaerobic, Selenate-Respiring Bacterium, Strain SES-3
Ronald S. Oremland,Jodi Switzer Blum,Charles W. Culbertson,Pieter T. Visscher,Laurence G. Miller,Phillip Dowdle,Frances E. Strohmaier +6 more
TL;DR: Results suggest that reduction of selenite to Se may proceed, in part, by some of the components of a dissimilatory system for sulfur oxyanions.
Journal ArticleDOI
Arsenic(III) fuels anoxygenic photosynthesis in hot spring biofilms from Mono Lake, California.
Thomas R. Kulp,Shelley E. Hoeft,M. Asao,Michael T. Madigan,James T. Hollibaugh,Jenny C. Fisher,John F. Stolz,Charles W. Culbertson,Laurence G. Miller,Ronald S. Oremland +9 more
TL;DR: Phylogenetic analysis indicates that microbial arsenic metabolism is ancient and probably extends back to the primordial Earth, and production of As(V) by anoxygenic photosynthesis probably opened niches forPrimordial Earth's first As( V)-respiring prokaryotes.
Journal ArticleDOI
Importance of methane-oxidizing bacteria in the methane budget as revealed by the use of a specific inhibitor
TL;DR: It is found that methanotrophic bacteria can consume more than 90% of the methane potentially available, and methylfluoride is reported to inhibit the oxidation of methane by methane monooxy-genase.
