Microbial dissimilatory sulfate reduction to sulfide is a predominant terminal pathway of
organic matter mineralization in the anoxic seabed. Chemical or microbial oxidation of the …

Advances in imaging technologies have revealed that many bacteria possess organelles
with a proteomically defined lumen and a macromolecular boundary. Some are bound by a …

Cells of most bacterial species are around 2 micrometers in length, with some of the largest
specimens reaching 750 micrometers. Using fluorescence, x-ray, and electron microscopy in …

Marine sediments are the largest carbon sink on earth. Nearly half of dark carbon fixation in
the oceans occurs in coastal sediments, but the microorganisms responsible are largely …

The recent discovery of a deep-water sulfur-cycling microbial biota in the∼ 2.3-Ga Western
Australian Turee Creek Group opened a new window to life's early history. We now report a …

Sulfate reduction and sulfur oxidation are very active in coastal sediments. Together they
shape the biogeochemistry and microbial ecology at hot places of organic matter …

According to average nucleotide identity (ANI) analysis of the complete genomes, strain
24S4–2 isolated from Antarctica is considered as a potential novel Arthrobacter species …

Due to their lithotrophic metabolisms, morphological complexity and conspicuous
appearance, members of the Beggiatoaceae have been extensively studied for more than …

Chemosynthesis increases alkalinity and facilitates stromatolite growth at methane seeps in
731 m water depth within the oxygen minimum zone (OMZ) in the northern Arabian Sea …

We investigated the impact of kelp deposition on the geochemistry and microbial community
composition of beach sands on the island of Helgoland (North Sea). The composition of the …
