title: Fine structure of Methanospirillum hungatii.
abstract: The fine structure of Methanospirillum hungatii was studied by electron microscopy. The topography of the cell wall and the mechanism of cell division are not typical of gram-positive or gram-negative bacteria. A novel architectural arrangement of cells in continuous spiral filaments is described. Filamentous cells are connected by spacers and enclosed within a rigid outer envelope. The unique ultrastructural features of cells and cell spacers were examined.
