Brine pool

A brine pool is a large area of brine on the ocean basin.

Candidatus

In prokaryote nomenclature, Candidatus (Latin for candidate of Roman office, named after the white gown worn by Roman senators) is a component of the taxonomic name for a bacterium or other prokaryote, that cannot be maintained in a microbiological culture collection.

Carbon fixation

Carbon fixation or сarbon assimilation is the conversion process of inorganic carbon (carbon dioxide) to organic compounds by living organisms.

Cold seep

A cold seep (sometimes called a cold vent) is an area of the ocean floor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool.

Electron donor

An electron donor is a chemical entity that donates electrons to another compound.

Humboldt Current

The Humboldt Current, also called the Peru Current, is a cold, low-salinity ocean current that flows north along the western coast of South America.

Hydrogen sulfide

Hydrogen sulfide is the chemical compound with the chemical formula H2S.

Inorganic compound

An inorganic compound is typically a chemical compound that lacks C-H bonds, that is, a compound that is not an organic compound, but the distinction is not defined or even of particular interest.

Lithotroph

Lithotrophs are a diverse group of organisms using inorganic substrate (usually of mineral origin) to obtain reducing equivalents for use in biosynthesis (e.g., carbon dioxide fixation) or energy conservation (i.e., ATP production) via aerobic or anaerobic respiration.

Mud volcano

A mud volcano or mud dome is a landform created by the eruption of mud or slurries, water and gases.

Redox

Redox (short for reduction–oxidation reaction) (pronunciation: or) is a chemical reaction in which the oxidation states of atoms are changed.

Reverse Krebs cycle

The reverse Krebs cycle (also known as the reverse tricarboxylic acid cycle, the reverse TCA cycle, or the reverse citric acid cycle) is a sequence of chemical reactions that are used by some bacteria to produce carbon compounds from carbon dioxide and water.

Sulfate-reducing microorganisms

Sulfate-reducing microorganisms (SRM) or sulfate-reducing prokaryotes (SRP) are a group composed of sulfate-reducing bacteria (SRB) and sulfate-reducing archaea (SRA), both of which can perform anaerobic respiration utilizing sulfate (SO42–) as terminal electron acceptor, reducing it to hydrogen sulfide (H2S).

Sulfur

Sulfur or sulphur is a chemical element with symbol S and atomic number 16.

Thiomargarita namibiensis

Thiomargarita namibiensis is a gram-negative coccoid Proteobacterium, found in the ocean sediments of the continental shelf of Namibia.

Thiotrichaceae

The Thiotrichaceae are a family of Proteobacteria, including Thiomargarita namibiensis, the largest known bacterium.

Vacuole

A vacuole is a membrane-bound organelle which is present in all plant and fungal cells and some protist, animal and bacterial cells.
