Autotrophic bacteria synthesize all their cell constituents using carbon dioxide as the carbon source. The most common pathways for synthesizing organic compounds from carbon dioxide are the reductive pentose phosphate ( Calvin) cycle, the reductive tricarboxylic acid cycle, and the acetyl-CoA pathway.

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. … WebLithoautotroph definition: (biology) A microbe that takes energy from reduced compounds of minerals .
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.
