Microbial Sulfur Cycle in Two Hydrothermal Chimneys on the Southwest Indian Ridge

mBio, 2014
Sulfur is an important element in sustaining microbial communities present in hydrothermal vents. Sulfur oxidation has been extensively studied due to its importance in chemosynthetic pathways in hydrothermal fields; however, less is known about sulfate ...

Quantitative analysis of the risk of hydrogen sulfide release from gas hydrates

Frontiers in Earth Science, 2023
The role that H2S plays in the global sulfur cycle has been studied extensively in recent years. This paper focuses on the influence of H2S released from gas hydrates on sulfur cycle and establishes a one-dimensional mathematical model to calculate the ...

Chemical Diversity and Biochemical Transformation of Biogenic Organic Sulfur in the Ocean

Frontiers in Marine Science, 2020
Organic sulfur compounds are not only essential for organismal survival but also indispensable for the sulfur cycle. Over the past few decades, dimethylsulfoniopropionate (DMSP) and dimethyl sulfide (DMS) cycling in the upper ocean have been well ...

Sulfate-reducing microorganisms in wetlands – fameless actors in carbon cycling and climate change

Frontiers in Microbiology, 2012
Freshwater wetlands are a major source of the greenhouse gas methane but at the same time can function as carbon sink. Their response to global warming and environmental pollution is one of the largest unknowns in the upcoming decades to centuries.
