The SUP05 clade of gammaproteobacteria (Thioglobaceae) comprises both primary
producers and primary consumers of organic carbon in the oceans. Host-associated …

A hallmark of the SUP05 clade of marine Gammaproteobacteria is the ability to use energy
obtained from reduced inorganic sulfur to fuel autotrophic fixation of carbon using RuBisCo …

Bacteria and archaea in the dark ocean (> 200 m) comprise 0.3–1.3 billion tons of actively
cycled marine carbon. Many of these microorganisms have the genetic potential to fix …

In deep-sea hydrothermal systems, super hot and reduced vent fluids from the subseafloor
blend with cold and oxidized seawater. Very unique and dense ecosystems are formed …

Background Heterotrophic microbes inhabiting the dark ocean largely depend on the
settling of organic matter from the sunlit ocean. However, this sinking of organic materials is …

Sulfur-oxidizing γ-proteobacteria are abundant in marine oxygen-deficient waters, and
appear to play a key role in a previously unrecognized cryptic sulfur cycle. Metagenomic …

In this study, we used comparative metaproteomics to investigate the metabolic activity of
microbial plankton inhabiting a seasonally hypoxic basin in the Northwest Atlantic Ocean …

Hydrothermal activity can generate numerous and diverse hydrocarbon compounds.
However, little is known about the influence of such hydrocarbons on deep-sea …

Hydrothermal vents are a well-known source of energy that powers chemosynthesis in the
deep sea. Recent work suggests that microbial chemosynthesis is also surprisingly …

The deep ocean (> 200 m depth) is the largest habitat on Earth. Recent evidence suggests
sulfur oxidation could be a major energy source for deep ocean microbes. However, the …
