chemoautotrophic
orchemotrophic
(of an organism) capable of manufacturing organic molecules from carbon dioxide and water by a process of CHEMOSYNTHESIS. For example, Thiobacillus oxidizes hydrogen sulphide to sulphur in order to produce the energy for chemosynthesis. Chemoautotrophic organisms are one form of AUTOTROPH, the other form displaying PHOTOTROPISM. Nitrate bacteria, such as Nitrobacter, and nitrite bacteria, such as Nitrosomonas, which contribute to the NITROGEN CYCLE, also grow chemoautotrophically Nitrobacter obtains the energy by oxidizing nitrite to nitrate, while Nitrosomonas oxidizes ammonia to nitrite.Collins Dictionary of Biology, 3rd ed. © W.
