The term Chemolithotrophy refers to the gain of energy for cell biosynthesis and maintenance from the oxidation of inorganic compounds (= electron donors), in the absence of light (Kelly and Wood, 2006). 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).
