Sulfur cycling in freshwater sediments: A cryptic driving force of iron ...

Abstract. Sulfur cycling in freshwater ecosystems has been previously considered minor, and the direct evidence of its impacts on iron and ...

The sulfur cycle of freshwater sediments: Role of thiosulfate - ASLO

Two-thirds of the S in the sulfide-thiosulfate “minicycle” remained at an oxidation state of −2. S2O32− is thus a key intermediate in the S cycle, both as a ...

The sulfur cycle of freshwater sediments: Role of thiosulfate - ASLO

S,0,2- is thus a key intermediate in the S cycle, both as a main product of anoxic sulfide oxidation and as a shunt between oxidative and reductive pathways.

Active microbial sulfur cycling in 13500-year-old lake sediments

Here we investigated the fate of buried S-compounds down to 10-m sediment depth representing the entire ~13.5 kya history of the sulfate-rich alpine Lake ...

Active microbial sulfur cycling in 13500-year-old lake sediments

S constitutes the biggest S pool in many freshwater sediments (Mitchell et al., 1981; Nriagu ... (B) involved in sulfur cycling in the sediment ...

Microbially Driven Sulfur Cycling in the River–Wetland–Ocean ...

In anoxic environments, sulfate reduction coupled with C degradation is a dominant respiration pathway in coastal sediments (Fig. 4A) [1,35,42, ...

Microbial Insights to Organic Sulfur Degradation in Freshwater ...

This review summarizes the current progress in the coupling of S cycling with nitrate-reducing pathways in freshwater sediments.

The Biogeochemical Sulfur Cycle of Marine Sediments - Frontiers

We here review the progress and current status in our understanding of the sulfur cycle in the seabed with respect to its microbial ecology, biogeochemistry, ...

Environmental Controls on Nitrogen and Sulfur Cycles in Surficial ...

Enhanced anthropogenic inputs of nitrogen (N) and sulfur (S) have disturbed their biogeochemical cycling in aquatic and terrestrial ecosystems. The N and S ...

Sulfur Cycling in the Water Columns of Lakes and Oceans - ProQuest

However, sulfur cycling in the water column is just as dynamic and exerts similar controls over biogeochemical cycles in lakes and oceans – although the exact ...

Genomic evidence for sulfur intermediates as new biogeochemical ...

Sulfur cycling genes were abundant at all depths and covaried with bacterial abundance. Genes for oxidative processes occurred in samples from ...

Complex Microbial Communities Drive Iron and Sulfur Cycling in ...

Sequences related to known sulfate reducers, such as Desulfococcus and Desulfosarcina, were most abundant within the top 10 cm of the sediment at station AB, ...
