Lithotrophy
Web21 apr. 2011 · Lithotrophy. Microbes use reduced inorganic substances, such as iron, sulfur, or magnesium from which to derive the chemical energy necessary to conduct biosynthesis. H 2 gas is the primary electron donor, though other compounds such as SO 3 2− S 4 O 6 2 −, S 0, Fe 2+, and Mn(II) are utilized as well [2]. Methanogenesis WebDefine them. a. Organotrophy: uses an organic electron donor (like glucose) and either an inorganic or organic terminal electron acceptor b. Lithotrophy: uses an inorganic electron donor (eats metal) and an inorganic or organic terminal acceptor c. Phototrophy: involved light capture by chlorophyll, usually coupled to splitting of H2S or H2O 4.

WebFigure 8.31. Diagram of simplified photosystem. Phototrophy involving an electron transport system includes photoexcitation of (bacterio)chlorophyll and generation of PMF which leads to synthesis of ATP as protons flow down their concentration gradient (“chemiomosis”), through the membrane-bound ATP synthase. WebThiobacillus A2 grown on thiosulphate lacks the capacity to transport succinate into the cells but is otherwise fully capable of oxidatively metabolizing succinate at a rapid rate. On the other hand, succinate-grown cells lack elements of the thiosulphate oxidation system; specifically, a special c-type cytochrome.Adaptation of thiosulphate-grown cells to …

WebLithotrophy runs through the Bacteria and the Archaea. If one considers methanogen oxidation of H 2 a form of lithotrophy, then probably most of the Archaea are lithotrophs. Lithotrophs are usually organized into "physiological groups" based on their inorganic substrate for energy production and growth (see Table 5 below). Table 5 ...
