Anaerobic Oxidation of Short-Chain Alkanes in Hydrothermal Sediments: Potential Influences on Sulfur Cycling and Microbial Diversity
(Frontiers Research Foundation, 2013)Short-chain alkanes play a substantial role in carbon and sulfur cycling at hydrocarbon-rich environments globally, yet few studies have examined the metabolism of ethane \((C_2)\), propane \((C_3)\), and butane \((C_4)\) ... -
Characterizing the distribution and rates of microbial sulfate reduction at Middle Valley hydrothermal vents
(Nature Publishing Group, 2013)Few studies have directly measured sulfate reduction at hydrothermal vents, and relatively little is known about how environmental or ecological factors influence rates of sulfate reduction in vent environments. A better ... -
Characterizing the Distribution and Rates of Microbial Sulfate Reduction at Middle Valley Hydrothermal Vents
(Nature Publishing Group, 2013-02-28)Few studies have directly measured sulfate reduction at hydrothermal vents, and relatively little is known about how environmental or ecological factors influence rates of sulfate reduction in vent environments. A better ... -
Enriched Iron(III)-Reducing Bacterial Communities are Shaped by Carbon Substrate and Iron Oxide Mineralogy
(Frontiers Media S.A., 2012)Iron (Fe) oxides exist in a spectrum of structures in the environment, with ferrihydrite widely considered the most bioavailable phase. Yet, ferrihydrite is unstable and rapidly transforms to more crystalline Fe(III) oxides ... -
Key Factors Influencing Rates of Heterotrophic Sulfate Reduction in Active Seafloor Hydrothermal Massive Sulfide Deposits
(Frontiers Media S.A., 2015)Hydrothermal vents are thermally and geochemically dynamic habitats, and the organisms therein are subject to steep gradients in temperature and chemistry. To date, the influence of these environmental dynamics on microbial ... -
Multiple sulfur isotope constraints on the modern sulfur cycle
(Elsevier BV, 2014)We present 28 multiple sulfur isotope measurements of seawater sulfate \((δ^{34}S_{SO_{4}} and Δ^{33}S_{SO_4})\) from the modern ocean over a range of water depths and sites along the eastern margin of the Pacific Ocean. ... -
Touring the Biogeochemical Landscape of a Sulfur-Fueled World
(GeoScienceWorld, 2010)Life, as recorded in almost every corner of the oceans and continents, has evolved to take advantage of chemical gradients. Organisms, both big and small, utilize reduction–oxidation (redox) reactions to gain the energy ...
