| | Purple bacteria - Wikipedia, the free encyclopedia |
| | Like most other photosynthetic bacteria, purple bacteria do not produce oxygen, because the reducing agent involved in photosynthesis is not water. | | | The others, called purple non-sulfur bacteria, typically use hydrogen although some may use other compounds in small amounts. | | | At one point these were considered families, but RNA trees show the purple bacteria make up a variety of separate groups, each closer relatives of non-photosynthetic proteobacteria than one another. |
