Advertisements
Description:
Bacteria which are able to manufacture their organic food from inorganic raw materials are known as chemoautotrophic bacteria. They use energy derived from exergonic chemical reactions involving oxidation of an inorganic substance present in the external medium.
Different types of chemoautotrophic bacteria are −
| Types | Energy source |
|---|---|
| Nitrifying Bacteria | Oxidation of ammonia to nitrite. |
| Sulphur Oxidising Bacteria | Oxidation of hydrogen sulphide to sulphur |
| Iron Bacteria | Oxidation of ferrous compounds to ferric forms. |
| Other chemosynthetic bacteria | Methane into carbon dioxide and water. Carbon monoxide to carbon dioxide. |
