Definition, Function and Examples - Biology Dictionary
网页2017年4月27日 — Chemoautotrophs are cells that create their own energy and biological materials from inorganic chemicals. In nature, “autotrophs” are organisms that don't need to eat because they make their own biological materials and energy. This term comes from the Greek “auto” for “self” and “troph” for “to eat” or “to feed.”.
5.1B: Chemoautotrophs and Chemohetrotrophs - Biology LibreTexts
网页2022年12月24日 — Learning Objectives. Compare chemoautotrophs and chemoheterotrophs. Chemotrophs are a class of organisms that obtain their energy through the oxidation of inorganic molecules, such as iron and magnesium. The most common type of chemotrophic organisms are prokaryotic and include both bacteria and fungi.
Chemotroph - Wikipedia
网页Chemoautotrophs are autotrophic organisms that can rely on chemosynthesis, i.e. deriving biological energy from chemical reactions of environmental inorganic substrates and synthesizing all necessary organic compounds from carbon dioxide.
Chemoautotroph Definition and Examples - Biology Online
网页2021年2月26日 — Chemoautotrophs are those that make their own food by chemosynthesis. Chemosynthesis is a process by which some organisms, such as certain bacteria, use chemical energy to produce carbohydrates.
Chemoautotroph - Biology Simple
网页2024年2月28日 — A chemoautotroph is a microorganism that utilizes inorganic chemicals, such as hydrogen sulfide or ferrous iron, as a source of energy to synthesize organic compounds. Unlike photoautotrophs, which rely on sunlight for energy, chemoautotrophs thrive in environments devoid of sunlight, such as …

Chemoautotrophy - an overview | ScienceDirect Topics
网页Chemoautotrophic production was demonstrated by incorporation of bicarbonate ion by the mat and by the presence of ribulose-1,5-biphosphate carboxylase-oxygenase, an enzyme characteristic of autotrophic organisms.
Chemoautotroph - an overview | ScienceDirect Topics
网页Most chemoautotrophs are bacteria or archaea, which live in different extreme habitats. The formatotroph Cupriavidus necator is a strictly chemoautotrophic bacterium using H 2 as the energy source for growth, and it can use not only formate but also CO 2 as the sole carbon source for autotrophic growth (Bowien and Kusian, 2002).
Chemotroph | biology | Britannica
网页Sulfur-oxidizing bacteria (chemoautotrophs) thrive in the warm, sulfur-rich water surrounding these cracks. The bacteria use reduced sulfur as an energy source for the fixation of carbon dioxide. Unlike all other known biological communities on Earth, the energy that forms the base of these deep-sea communities comes from… Read More.
Chemoautotroph - SpringerLink
网页Chemoautotrophs are organisms that obtain their energy from a chemical reaction (chemotrophs) but their source of carbon is the most oxidized form of carbon, carbon dioxide (CO 2). The best known chemoautotrophs are the chemolithoautotrophs that use inorganic energy sources, such as ferrous iron, hydrogen, hydrogen sulfide, elemental sulfur or ...
