Lithotrophs and organotrophs
Did you know?
WebOrganotroph. Tools. An organotroph is an organism that obtains hydrogen or electrons from organic substrates. This term is used in microbiology to classify and describe organisms based on how they obtain electrons for their respiration processes. Some organotrophs such as animals and many bacteria, are also heterotrophs. WebOrganotroph = use organic source for electrons (to release into ETC to make ATP) Lithotroph = use reduced inorganic mlcls (reduced Fe2+, metals) for electron …
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 … Meer weergeven The term was suggested in 1946 by Lwoff and collaborators.
