Microbial dissimilatory sulfur metabolism utilizing dissimilatory sulfite reductases (Dsr)
influenced the biochemical sulfur cycle during Earth's history and the Dsr pathway is thought …

Since the beginning of unicellular life, dissimilation reactions of autotrophic sulfur bacteria
have been a crucial part of the biogeochemical sulfur cycle on Earth. A wide range of sulfur …

Previous studies of microbial communities in subseafloor sediments reported that microbial
abundance and diversity decrease with sediment depth and age, and microbes dominating …

oxidation–reduction force for matter transformation and energy communication. The most …

Abstract Lost Hammer Spring, located in the High Arctic of Nunavut, Canada, is one of the
coldest and saltiest terrestrial springs discovered to date. It perennially discharges anoxic (< …

Background Biofilms in sulfide-rich springs present intricate microbial communities that play
pivotal roles in biogeochemical cycling. We studied chemoautotrophically based biofilms …

Abstract Background Gypsum Hill Spring, located in Nunavut in the Canadian High Arctic, is
a rare example of a cold saline spring arising through thick permafrost. It perennially …

Biogas serves as a crucial renewable energy vector to ensure a more sustainable energy
future. However, the presence of hydrogen sulfide (H 2 S) limits its application in various …

The microorganisms responsible for driving the Anammox and Sammox processes may
have ancient origins and remain poorly understood. In this research, we enriched the …

The diversity and distribution patterns of the abundant and rare microbial sub-communities
