Methanospirillum hungatii bacteria

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
