Ecophysiological Features Shape the Distribution of Prophages and CRISPR in Sulfate Reducing Prokaryotes

Microorganisms, 2021
Sulfate reducing prokaryotes (SRP) are a phylogenetically and physiologically diverse group of microorganisms that use sulfate as an electron acceptor. SRP have long been recognized as key players of the carbon and sulfur cycles, and more recently, they ...

The effects of organic matter and anaerobic oxidation of methane on the microbial sulfate reduction in cold seeps

Frontiers in Marine Science, 2023
Cold seep sediments are dominated by intensive microbial sulfate reduction coupled to anaerobic oxidation of methane. However, the contribution proportion between this process and the role of organic matter has remained enigmatic.

Enhanced sulfate reduction with acidogenic sulfate-reducing bacteria [PDF]

Journal of Hazardous Materials, 2008
Sulfate reduction in a continuous flow, acidogenic reactor using molasses wastewater as the carbon source was studied at varying chemical oxygen demand/sulfate (COD/SO4(2-)) ratios. At a critical COD/SO4(2-) ratio of 2.7, neither COD nor sulfate were in excess for extra production of ethanol or acetate in the reactor.

Microbial sulfate reduction potential in coal-bearing sediments down to ~2.5 km below the seafloor off Shimokita Peninsula, Japan

Frontiers in Microbiology, 2016
Sulfate reduction is the predominant anaerobic microbial process of organic matter mineralization in marine sediments, with recent studies revealing that sulfate reduction not only occurs in sulfate-rich sediments, but even extends to deeper ...

Key factors influencing rates of heterotrophic sulfate reduction in active seafloor hydrothermal massive sulfide deposits

Frontiers in Microbiology, 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 sulfate reduction has not been

The pH and pCO2 dependence of sulfate reduction in shallow-sea hydrothermal CO2 – venting sediments (Milos Island, Greece)

Frontiers in Microbiology, 2013
Microbial sulfate reduction is a dominant process of organic matter mineralization in sulfate-rich anoxic environments at neutral pH. Recent studies have demonstrated sulfate reduction in low pH environments, but investigations on the microbial activity ...

Sulfate and dissolved sulfide variation under low COD/Sulfate ratio in Up-flow Anaerobic Sludge Blanket (UASB) treating domestic wastewater

Revista Ambiente & Água, 2012
In this study, the dynamics of sulfate reduction and dissolved sulfide generation (S2-, HS-, H2Saq) in liquid phase was evaluated in an UASB reactor treating domestic wastewater with low COD/Sulfate content.
