The term chemolithotrophy describes the energy metabolism of bacteria that can, in the absence of light, use the oxidation of inorganic substances as a source of energy for cell biosynthesis and maintenance (Rittenberg, 1969).

Some microbes are chemolithoheterotrophs, using an inorganic chemical for their energy and electron needs, but relying on organic chemicals in the environment for their carbon needs. Microbiol. Antonie van Leeuwenhoek Journal of Microbiology and Serology 38:457478. Using a non-oxygen acceptor allows chemolithotrophs to have greater diversity and the ability to live in a wider variety of environments, although they sacrifice energy production. 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. Marine ecology John Wiley & Sons London. These chemoautotrophs oxidize ammonia (NH3) to nitrate (NO3-).
