Microbiology, 77(2), 235239. doi:10.1134/S0026261708020185 Definitions Heterotrophic bacteria - bacteria that use organic (carbon-containing) compounds as a source of energy and carbon. This characteristic distinguishes heterotrophic bacteria from chemoautotrophic (chemosynthesizing) and photoautotrophic (photosynthesizing) bacteria, which assimilate CO2 as a source of carbon. The overwhelming number of known species of bacteria, both aerobic and anaerobic, are heterotrophic. Many heterotrophic bacteria utilize sugar, alcohol, and organic acids. However, there are specialized heterotrophic bacteria capable also of decomposing cellulose, lignin, chitin, keratin, hydrocarbons, phenol, and other substances. Heterotrophic bacteria take an active part in the natural recycling of substances.
