The role of microorganisms in the weathering of minerals has long been recognized ().More recent interest in the role of Fe(II)-oxidizing bacteria (FeOB) has been driven by the recognition that Fe(II)-bearing mineral phases, such as Fe(II)-silicates and pyrite, represent a potential wealth of energy to fuel chemolithotrophic metabolisms, both terrestrially and on other rocky planetary bodies .

Unauthorized use of these marks is strictly prohibited. The term chemolithotroph literally means "rock eaters" and is used to designate organisms that generate energy by the oxidation of inorganic molecules for biosynthesis or energy conservation via aerobic or anaerobic respiration. 180 29752982, Whittenbury, R., Kelly, D.

Communities on biochar and MEBs were dominated by a novel Gammaproteobacterium. The smaller the distance between the two, the less ATP that will be formed. Chemoheterotrophs (or chemotrophic heterotrophs) are unable to fix carbon to form their own organic compounds. Soc. PDF Chemolithotroph Bacteria: From Biology to Application in Medical Sciences Download preview PDF. Later, the term would include also the chemoorganoautotrophy, that is, it can be seen as a synonym of chemoautotrophy.[4][5]. We therefore analyzed the diversity and functions of bacterial communities on the surfaces of one biochar and two different MEBs after a 140-day incubation in soil.
