| Morphology | Methanoplanus |
| CELLULAR |
| Staining | |
| Morphology | Cells are angular, crystallike plates 0.07-0.30 um thick, 1.6-3.4 um long and 1.5 um wide and occur singlyThe cells are sometimes branched, without septa. |
| Motility | Flagellate |
| Specialized structures | The cell envelope shows a hexagonal surface pattern No sacculus is present. |

| Growth Parameters | Methanoplanus |
| PHYSIOLOGICAL |
| Tropism | Chemolithotrophic, growing on H2 and CO2 or formate |
| Oxygen | Strictly anaerobic |
| pH | |
| Temperature | Optimum temperature: 32-40`C; maximum: 41`C; minimum: 16`C. |
| Requirements | Growth occurs in 0.4 and 6% NaCl.. |
| Products | methane In the presence of molecular sulfur, H2S is formed, in addition to H2 and CO2 (Stetter and Gaag 1983). |
| Enzymes | |
| Unique features | No growth occurs on methanol or methylamines. (Wildgruber et al. 1982). Cells are resistant to vancomycin, penicillin, kanamycin and tetracycline. |
