/ˌkiːməʊɔːˈɡanəˌtrəʊfi/, /ˌkɛməʊɔːˈɡanəˌtrəʊfi/, U.S. /ˌkimoʊɔrˈɡænəˌtroʊfi/, /ˌkɛmoʊɔrˈɡænəˌtroʊfi/ Biology.
A form of chemotrophic nutrition in which biosynthesis requires the oxidation of one or more of a variety of organic compounds acting as electron donors. Cf. chemolithotrophy n.In such nutrition, organic compounds often also provide a source of carbon (chemoheterotrophy), and the terms are sometimes confused.
