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

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