chemosynthesis

 [ke″mo-sin´thĕ-sis]
the building up of chemical compounds under the influence of chemical stimulation, specifically the formation of carbohydrates from carbon dioxide and water as a result of energy derived from chemical reactions. adj., adj chemosynthet´ic.

chemosynthesis

(kē′mō-sĭn′thĭ-sĭs, kĕm′ō-)
n.
The synthesis of organic compounds by certain bacteria, especially in deep-sea hydrothermal vents, using energy obtained from the chemical oxidation of simple inorganic compounds. Chemosynthesis is thought to have been used by the first forms of life on Earth.

chemosynthesis

the process of obtaining energy and synthesizing organic compounds from simple inorganic reactions. This is brought about by special methods of respiration involving the oxidation of inorganic compounds such as iron, ammonia and hydrogen sulphate, and is carried out by several kinds of CHEMOAUTOTROPHIC bacteria. See AUTOTROPH, NITROGEN CYCLE.

The discoveries include the identification of volcanic and hydrothermal processes at mid-ocean ridge crests in different geographic settings and tectonic environments, and the presence of previously unknown, abyssal biological communities with a rich diversity of species that are sustained by chemosynthetic processes derived from hot hydrothermal vents rather than the photosynthetic process that sustains most life on land.
These "cold seeps" are of interest to biologists as well as geologists because of the chemosynthetic communities that surround them.
Colleen Cavanaugh was one of her most exemplary students: Brilliant and exuberant, her work in graduate school showed that the vent animals, such as giant tube worms, depend on their symbiotic chemosynthetic bacteria for energy, rather than on food from sunlight.
Following these finds it seemed clear that such communities occur only along specific geological features, such as mid-ocean ridges and continental margins; the vast sediment plains of the abyss must indeed be deserts, devoid of even an occasional chemosynthetic oasis.
ABSTRACT Carbon fixation by sulfur-oxidizing chemosynthetic bacteria forms the base of the food chain in deep-sea (diffuse-flow) hydrothermal vent ecosystems.
