Chemoautotrophic and Chemolithotrophic Bacteria

A chemotroph is an organism that obtains energy by the oxidation of electron donors in their environments. These molecules can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which use photons. Chemotrophs can be either autotrophic or heterotrophic. Chemotrophs can be found in areas where electron donors are present in high concentration, for instance around hydrothermal vents. WebA chemolithoautotroph is an autotrophic microorganism that obtains energy by oxidizing inorganic compounds. Most chemolithotrophs are autotrophs. Examples of relevant inorganic electron donors include hydrogen, hydrogen sulfide, ferrous iron, and ammonia. Winogradsky described the concept of chemolithoautotrophy for the first time while ... tesis oss rba
