Contrast | The photosynthetic or phototrophic bacteria can be broken into two major groups; the Anoxygenic Phototrophic Bacteria that grow under anaerobic conditions and theOxygenic PhototrophicBacteria that use oxygen to carry out photosynthesis |

Morphology | cells oval to spherical in diameter 3-8 um in diameter |
Motility | |
Specialized structures | original isolates are amorpous aggeagates of cells with gas vesicles, held together by an amorphous "mucilagenous" sheath |
Division | binary fission is in 3 planes but the cells are irregularly oriented in aggregates |
