Methanospirillum hungatii bacteria
Numéro d’image : 11524032
| Archaebacteria. Coloured transmission electron micrograph of the archaebacteria Methanospirillum hungatii. An elongated Gram-negative cell,it is here undergoing cell division. Typically,these thin cells are spiral shaped. Two other cells are cut through in cross-section. Methanospirillum hungatii is an anaerobe living in oxygen-free conditions. It is a methanogen in that it metabolizes carbon dioxide and hydrogen to produce methane. Like all bacteria,archaebacteria are single celled prokaryotes without a nucleus. Archaebacteia,however,have very primitive ancestors not closely related to other bacteria. Magnification: x29,000 at 6x7cm size. Magnification: x100,000 at 8x10 inch size | |
