| Morphology | Chloroflexus aurantiacus |
| CELLULAR |
| Staining | Gram-negative |
| Morphology | Filaments of indefinite length; cells 0.5 to about 1.0 um in diameter, 2 to about 6 um in length; none differentiated |
| Motility | Motile by gliding (0.01-0.04 um/s); no flagella. |
| Specialized structures | Cell division by fission, no branching. No internal proliferations of cell membrane, except mesosomes; chlorosomes present when anaerobically grown. Thin sheath sometimes present. |

| Growth Parameters | Chloroflexus aurantiacus |
| PHYSIOLOGICAL |
| Tropism | Primarily photoheterotrophic, secondarily photoautotrophic (probably not all strains) and chemoheterotrophic (not all strains). Several carbon sources utilized: eg. acetate, glycerol, glucose, pyruvate and glutamate. |
| Oxygen | Anaerobic and facultatively aerobic (some). |
| pH | |
| Temperature | |
| Requirements | |
| Products | Bacteriochlorophylls a and c present under anaerobic conditions; carotenoids include B- and y-carotene and hydroxy- and oxo-derivative and glycosides of both. |
