| Growth Parameters | Rhodopseudomonas |
| PHYSIOLOGICAL |
| Tropism | Photoheterotrophic growth with a number of organic carbon compounds as carbon source and electron donor is the preferred mode of growth. Photoautotrophic growth may be possible under anaerobic conditions with hydrogen, thiosulfate or sulfide as electron donor. Chemotrophic growth under microaerobic to aerobic conditions is possible by some species. |
