Lithotrophs are a diverse group of organisms using an 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. [1] .

2024年3月11日 · Organotrophs derive energy from organic compounds, whereas lithotrophs utilize inorganic substances. Organotrophs are organisms that oxidize organic molecules, such as carbohydrates and fats, to obtain energy. They play a crucial role in the decomposition of organic matter and the cycling of nutrients within ecosystems.

A lithotroph is a microorganism that uses inorganic substrates as a source of electron donors to drive energy acquisition, using either organic carbon or carbon dioxide as a source of carbon for constructing cellular materials (Ehrlich and Newman 2008).

…widely distributed among prokaryotes is lithotrophy (from the Greek word lithos, meaning “stone”), the ability to obtain energy by the transfer of electrons from hydrogen gas to inorganic acceptors. It has been proposed that the earliest forms of life on Earth used lithotrophic metabolism and that photosynthesis was a later…

2021年2月16日 · Lithotrophs (“litho” means “rock”) are chemotrophs that get energy from inorganic compounds, including hydrogen sulfide (H 2 S) and reduced iron. Lithotrophy is unique to the microbial world. The strategies used to obtain both carbon and energy can be combined for the classification of organisms according to nutritional type.

2024年3月8日 · Autotrophs produce their own food using light or chemical energy, while lithotrophs derive energy from inorganic substances. Autotrophs are organisms capable of synthesizing their own food from inorganic substances using light (photoautotrophs) or chemical energy (chemoautotrophs).

Explain why an organism like Desulfovibrio could grow as an anaerobic lithotroph, while Acidithiobacillus ferrooxidans growing on FeSO 4 would be an obligate aerobe. Explain why most lithotrophs, with the exception of those that oxidize H 2, must expend energy to make the reduced cofactors for biosynthesis.

2024年10月27日 · Explore the diverse world of lithotrophy, focusing on its types, electron donors, and its role in environmental processes. Lithotrophy is a fascinating metabolic process where certain microorganisms derive energy from inorganic compounds.

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.

In biology terms the difference between autotroph and lithotroph is that autotroph is any organism that can synthesize its food from inorganic substances, using heat or light as a source of energy while lithotroph is an organism that obtains its energy from inorganic compounds (such as ammonia) via electron transfer.
