WebLithotrophy: Electron Donors and Acceptors - Different from chemoorganotrophs - Remember lithotrophs are NOT catabolize organic compounds (carbon) to generate ATP - Instead they use oxidation-reduction of inorganic compounds to generate the proton motive force for ATP production. Iron ... WebIn contrast, the microbial mat clone sequences clustered with sequences from obligate lithotrophs representative of form IA rbcL. Clone sequences from volcanic sites fell within the form IC clade, suggesting that these sites were dominated by facultative lithotrophs, an observation consistent with biogeochemical patterns at the sites.

WebLithotrophs are microorganisms that use inorganic compounds as electron donors to conserve energy for growth. Overview A lithotroph is a microorganism that uses … WebChemolithotrophs use a variety of inorganic compounds as electron donors, with the most common substances being hydrogen gas, sulfur compounds (such as sulfide and sulfur), nitrogen compounds (such as ammonium and nitrite), and ferrous iron. Hydrogen oxidizers – these organisms oxidize hydrogen gas (H2) with the use of a hydrogenase enzyme.
