A hot origin of dissimilatory sulfite reduction catalyzed by DsrAB in the Paleoarchean Era [PDF]

mLife
Dissimilatory sulfite reduction (DSR) has been essential to microbial energy metabolism in the biogeochemical sulfur cycle since the Paleoarchean Era.

Characterization of DsrD and its interaction with the DsrAB dissimilatory sulfite reductase [PDF]

Protein Science
AbstractMicrobial dissimilatory sulfate reduction is a key process in the global sulfur and carbon cycles in anoxic ecosystems. In this anaerobic respiration, sulfate is phosphorylated and reduced to sulfite, which is further reduced to a DsrC‐trisulfide by the dissimilatory sulfite reductase DsrAB.

Cryptic sulfur cycling in the deep biosphere of ferruginous Lake Towuti, Indonesia [PDF]

Frontiers in Microbiology
Lake Towuti, Sulawesi, Indonesia is an ancient tectonic lake, exhibiting iron-rich, sulfate-poor anoxic deep waters. Temporal variations in water column stratification led to sediment accumulation under variable redox conditions.

Environmental selection and evolutionary process jointly shape genomic and functional profiles of mangrove rhizosphere microbiomes

mLife, 2023
Mangrove reforestation with introduced species has been an important strategy to restore mangrove ecosystem functioning. However, how such activities affect microbially driven methane (CH4), nitrogen (N), and sulfur (S) cycling of rhizosphere microbiomes

Single-Cell Genome and Group-Specific dsrAB Sequencing Implicate Marine Members of the Class Dehalococcoidia (Phylum Chloroflexi) in Sulfur Cycling [PDF]

mBio, 2016
The marine subsurface sediment biosphere is widely inhabited by bacteria affiliated with the class Dehalococcoidia (DEH), phylum Chloroflexi, and yet little is known regarding their metabolisms. In this report, genomic content from a single DEH cell (DEH-

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

Nature 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.

Study on the Source and Microbial Mechanisms Influencing Heavy Metals and Nutrients in a Subtropical Deep-Water Reservoir [PDF]

Microorganisms
Reservoirs are hotspots for the coupling of nutrients and heavy metals, and they substantially modify the compositions and spatiotemporal distributions of microorganisms in fluvial systems.
