(kē'mō-aw-tō-trō'fik)
Pertaining to a chemoautotroph.

chemoautotrophic

or

chemotrophic

(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.

Studies conducted in the laboratory of microbiologist Jody Deming (University of Washington) revealed that the gill tissues of large vesicomyid clams and bone-encrusting mussels contain substantial amounts of enzymes that are characteristic of chemoautotrophic metabolism; transmission electron microscopy indicated that these enzymes were associated with endosymbiotic bacteria.
