Sulfur cycling in freshwater sediments: A cryptic driving force of iron deposition and phosphorus mobilization

Science of the Total Environment, 2019
Sulfur cycling in freshwater ecosystems has been previously considered minor, and the direct evidence of its impacts on iron and phosphorus cycles in freshwater sediments remains unclear.

Nitrogen and sulfur cycling and their coupling mechanisms in eutrophic lake sediment microbiomes

Science of the Total Environment
Microorganisms play important roles in the biogeochemical cycles of lake sediment. However, the integrated metabolic mechanisms governing nitrogen (N) and sulfur (S) cycling in eutrophic lakes remain poorly understood. Here, metagenomic analysis of field

Sulfur Cycling and the Intestinal Microbiome

Digestive Diseases and Sciences, 2017
In this review, we focus on the activities transpiring in the anaerobic segment of the sulfur cycle occurring in the gut environment where hydrogen sulfide is produced. While sulfate-reducing bacteria are considered as the principal agents for hydrogen sulfide production, the enzymatic desulfhydration of cysteine by heterotrophic bacteria also ...

Stable Isotopic and Metagenomic Analyses Reveal Microbial-Mediated Effects of Microplastics on Sulfur Cycling in Coastal Sediments.

Environmental Science and Technology, 2023
Microplastics are readily accumulated in coastal sediments, where active sulfur (S) cycling takes place. However, the effects of microplastics on S cycling in coastal sediments and their underlying mechanisms remain poorly understood.

Geochemical evidence for cryptic sulfur cycling in salt marsh sediments [PDF]

Earth and Planetary Science Letters, 2016
Cryptic sulfur cycling is an enigmatic process in which sulfate is reduced to some lower-valence state sulfur species and subsequently quantitatively reoxidized; the rate and microbial energetics of this process and how prevalent it may be in the ...

Biochar decreases Cd mobility and rice (Oryza sativa L.) uptake by affecting soil iron and sulfur cycling.

Science of the Total Environment, 2022
Biochar has been used as an amendment in Cd-contaminated soils. However, the mechanisms of which biochar reduce Cd mobility and rice (Oryza sativa L.) Cd uptake by modifying the iron and sulfur cycling in soil has rarely been addressed in the literature.

Boosting Bi‐Directional Redox of Sulfur with Dual Metal Single Atom Pairs in Carbon Spheres Toward High‐Rate and Long‐Cycling Lithium–Sulfur Battery

Advanced Energy Materials, 2023
The severe shuttle effect of polysulfides and sluggish redox kinetics are the main problems that hinder the practical applications of lithium–sulfur (Li–S) batteries. In this study, dual metallic single atom pairs are implanted into carbon nanospheres to
