Overlooked role of heterotrophic prokaryotes in sulfur oxidation makes the sediment of the Bohai Sea a sufficient sink of hydrogen sulfide [PDF]

open access: yesmBio
Marine sediments are the active sites for the biogeochemical cycling of sulfur. Sulfate is used as a major terminal electron acceptor for the anaerobic oxidation of organic compounds in deep sediments, and the produced sulfide is normally oxidized back ...

Sulfur Oxidation in the Acidophilic Autotrophic Acidithiobacillus spp. [PDF]

open access: yesFrontiers in Microbiology, 2019
Sulfur oxidation is an essential component of the earth’s sulfur cycle. Acidithiobacillus spp. can oxidize various reduced inorganic sulfur compounds (RISCs) with high efficiency to obtain electrons for their autotrophic growth.

High Potential for Anaerobic Microbial Sulfur Oxidation in Oil Sands Tailings Ponds [PDF]

open access: yesMicroorganisms, 2021
The biogenic production of toxic H2S gas in sulfate-rich oil sands tailings ponds is associated with strong environmental concerns. Beside precipitation into sulfide minerals and chemical re-oxidation, microbial sulfur oxidation may catalyze sulfide re ...

Sulfur oxidation and implications for oxygen consumption in Base Mine Lake, the first pilot oil sands pit lake in the Athabasca oil sands region [PDF]

open access: yesFrontiers in Microbiology
Base Mine Lake (BML) is the first pilot scale oil sands pit lake in the Athabasca Oil Sands Region (AOSR). Following a whole lake alum addition in September of 2016, a seasonally recurring zone of anoxia developed in the late summer hypolimnion of the ...

Sulfur oxidation and reduction are coupled to nitrogen fixation in the roots of the salt marsh foundation plant Spartina alterniflora [PDF]

open access: yesNature Communications
Heterotrophic activity, primarily driven by sulfate-reducing prokaryotes, has traditionally been linked to nitrogen fixation in the root zone of coastal marine plants, leaving the role of chemolithoautotrophy in this process unexplored.

Diversity and Distribution of Sulfur Oxidation-Related Genes in Thioalkalivibrio, a Genus of Chemolithoautotrophic and Haloalkaliphilic Sulfur-Oxidizing Bacteria [PDF]

open access: yesFrontiers in Microbiology, 2019
Soda lakes are saline alkaline lakes characterized by high concentrations of sodium carbonate/bicarbonate which lead to a stable elevated pH (>9), and moderate to extremely high salinity. Despite this combination of extreme conditions, biodiversity in

Elucidating the mechanism of thiosulfate oxidation by a novel two-component system SulRS in deep-sea Campylobacterota [PDF]

open access: yesiScience
Summary: Members of the phylum Campylobacterota, which dominate deep-sea hydrothermal vent ecosystems, typically harbor the ability for thiosulfate oxidation through a complete sulfur oxidation (Sox) system encoded by the soxABXY1Z1 and soxCDY2Z2 gene ...

Physiology, Taxonomy, and Sulfur Metabolism of the Sulfolobales, an Order of Thermoacidophilic Archaea

open access: yesFrontiers in Microbiology, 2021
The order Sulfolobales (phylum Crenarchaeota) is a group of thermoacidophilic archaea. The first member of the Sulfolobales was discovered in 1972, and current 23 species are validly named under the International Code of Nomenclature of Prokaryotes.
