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 . But, chemoautotrophs and chemolithotrophs do not usually face competition from other microorganisms , so the energy they are able to obtain is sufficient to sustain their existence. Biochemical reaction mechanisms in sulphur oxidation by chemosynthetic bacteria. The evolution of bacteria to exist as chemoautotrophs or chemolithotrophs has allowed them to occupy niches that Only bacteria are chemolithotrophs.
