Lithoautotrophs
WebLithoautotrophs are prokaryotic bacteria and archeobacteria, and include many organisms that live in extreme environments such as hot springs, geothermal vents, and fissures deep within the Earth’s crust. Lithoautotrophs are important in the weathering of rock, the regeneration of soil, and the biogeochemical cycling of sulfur and nitrogen.

WebLithoautotroph definition: (biology) A microbe that takes energy from reduced compounds of minerals . WebMicroorganisms which are known as lithoautotrophs oxidize inorganic substances such as H2S as source of energy. The H2S-oxidizing lithoautotrophs can be used for natural …
WebA lithoautotroph is a microbe which derives energy from reduced compounds of mineral origin. They may also be referred to as chemolithoautotrophs, a type of lithotrophs, … 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. While lithotrophs in the broader sense include photolithotrophs like plants, chemolithotrophs are exclusively microorganisms; no known macrofauna possesses the ability to use inorganic compounds as electron sources. …
Webmixotrophically. These organisms are obligate lithoautotrophs with the exception of Nitrobacter, which can grow heterotrophi-cally. Nitrobacter has been shown to grow anaerobically by dissi-milatory nitrate reduction (Freitag et al., 1987). MORPHOLOGICAL CHARACTERISTICS The nitrite oxidizers are a diverse group of rods, cocci, and spi-rilla. Web1 sep. 2005 · Lithoautotrophs often occupy habitats at the interface between two environments with divergent redox chemistry. In cases where rocks are directly exposed to the seafloor (at ∼1.5–2 km depth below the surface of the ocean), or in rock habitats in the oceanic subsurface (down to ∼500 m subseafloor depth), chemical energy sources for …
