Dysoxic marine waters (DMW,< 1 μM oxygen) are currently expanding in volume in the
oceans, which has biogeochemical, ecological and societal consequences on a global …

Symbiotic N2-fixing microorganisms have a crucial role in the assimilation of nitrogen by
eukaryotes in nitrogen-limited environments,–. Particularly among land plants, N2-fixing …

Environmental metaproteomics is a rapidly advancing field that provides insights into the
structure, dynamics, and metabolic activity of microbial communities. As the field is still …

Sulfur is the tenth most abundant element on Earth (Steudel & Chivers, 2019) and is cycled
dynamically between the geosphere and biosphere. Sulfate or sulfide in water and soil and …

Metal‐sulfides are wide‐spread in marine benthic habitats. At deep‐sea hydrothermal vents,
they occur as massive sulfide chimneys formed by mineral precipitation upon mixing of …

Mitochondria are key intracellular targets of hypoxia-reoxygenation (H/R) stress due to their
central role in generation of ATP and reactive oxygen species (ROS). Intertidal oysters …

Bacteria of the genus Sulfurimonas within the class Campylobacteria are predominant in
global deep-sea hydrothermal environments and widespread in global oceans. However …

Background Deep-sea hydrothermal vents are highly productive biodiversity hotspots in the
deep ocean supported by chemosynthetic microorganisms. Prominent features of these …

Deep-sea hydrothermal vents may provide one of the largest reservoirs on Earth for
hydrogen-oxidizing microorganisms. Depending on the type of geological setting …

Most autotrophs use the Calvin–Benson–Bassham (CBB) cycle for carbon fixation. In
contrast, all currently described autotrophs from the Campylobacterota (previously …
