WebUne souche de Rhizobium japonicum (6-3I1b6) positive pour l'absorption d'hydrogène s'est avérée capable de croître de façon chimiolithotrophe en absence d'oxygène, en utilisant du nitrate comme accepteur d'électron. La réduction dissimilatrice du nitrate survient au cours de la croissance, ce qui est démontré par la disparition du nitrate du milieu et la … The term "chemolithotrophy" refers to a cell's acquisition of energy from the oxidation of inorganic compounds, also known as electron donors. This form of metabolism is believed to occur only in prokaryotes and was first characterized by Ukrainian microbiologist Sergei Winogradsky. [7] Habitat of … See more 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., See more Lithotrophs participate in many geological processes, such as the formation of soil and the biogeochemical cycling of carbon, nitrogen, and other elements. Lithotrophs also associate with the modern-day issue of acid mine drainage. Lithotrophs may be present in a variety … See more • Autotroph • Electrolithoautotroph • Endolith • Heterotroph • Microbial metabolism • Organotroph See more The term was suggested in 1946 by Lwoff and collaborators. See more Lithotrophs consume reduced inorganic compounds (electron donors). Chemolithotrophs A chemolithotroph is able to use inorganic reduced … See more It has been suggested that biominerals could be important indicators of extraterrestrial life and thus could play an important role in the search for past or present life on the planet Mars.
