Influence of salinity on the diversity and composition of carbohydrate metabolism, nitrogen and sulfur cycling genes in lake surface sediments [PDF]
Frontiers in Microbiology, 2022 Exploring functional gene composition is essential for understanding the biogeochemical functions of lakes. However, little is known about the diversity and composition of biogeochemical cycling genes and their influencing factors in saline lakes.

Microbial Diversity and Sulfur Cycling in an Early Earth Analogue: From Ancient Novelty to Modern Commonality [PDF]
mBio, 2022 Life emerged and diversified in the absence of molecular oxygen. The prevailing anoxia and unique sulfur chemistry in the Paleo-, Meso-, and Neoarchean and early Proterozoic eras may have supported microbial communities that differ from those currently ...

Fish growth enhances microbial sulfur cycling in aquaculture pond sediments [PDF]
Microbial Biotechnology, 2020 Summary Microbial sulfate reduction and sulfur oxidation are vital processes to enhance organic matter degradation in sediments. However, the diversity and composition of sulfate‐reducing bacteria (SRB) and sulfur‐oxidizing bacteria (SOB) and their ...

Microbial diversity involved in iron and cryptic sulfur cycling in the ferruginous, low-sulfate waters of Lake Pavin. [PDF]
PLoS ONE, 2019 Both iron- and sulfur- reducing bacteria strongly impact the mineralogy of iron, but their activity has long been thought to be spatially and temporally segregated based on the higher thermodynamic yields of iron over sulfate reduction.

The evolution and spread of sulfur cycling enzymes reflect the redox state of the early Earth. [PDF]
Sci Adv, 2023 The biogeochemical sulfur cycle plays a central role in fueling microbial metabolisms, regulating the Earth’s redox state, and impacting climate. However, geochemical reconstructions of the ancient sulfur cycle are confounded by ambiguous isotopic ...

Novel taxa of Acidobacteriota implicated in seafloor sulfur cycling. [PDF]
ISME J, 2021 Acidobacteriota are widespread and often abundant in marine sediments, yet their metabolic and ecological properties are poorly understood. Here, we examined metabolisms and distributions of Acidobacteriota in marine sediments of Svalbard by functional ...

Vegetation restoration restructures soil sulfur allocation and sulfur-cycling functional potential in the Mu Us Sandy Land [PDF]
Frontiers in MicrobiologyVegetation restoration in semi-arid sandy ecosystems can alter soil sulfur cycling not only through changes in sulfur stocks, but also through shifts in the partitioning between organic sulfur and sulfate and their microbial regulation.
