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] .

无机营养生物包括化能无机营养菌（Chemlithotroph）和 光能无机营养菌 （Photolithotroph）。 顾名思义，两者的区别在于能量的获得方式，但在“无机”方面是相通的。 无机营养生物（lithotroph）属于化学营养生物，是“有高度合成能力，利用二氧化碳或碳酸盐作为唯一碳源，利用氨，氨盐，硝酸盐或亚硝酸盐等作为氮源”的细菌。

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).

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.

…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…

2024年3月8日 · On the other hand, lithotrophs, a subset of autotrophs, specifically obtain their energy by oxidizing inorganic substances, such as minerals or gases like hydrogen sulfide. Photoautotrophs, a type of autotroph, utilize sunlight to convert carbon dioxide and water into glucose and oxygen through photosynthesis, a process vital for life on Earth.

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.

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.

Overview 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 ).

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.
