Abstract: | Abstract Depending on the culture conditions, Pyrodictium occultum cells revealed two different types of fibers with significant differences in their width in the electron microscope. During growth on elemental sulfur preferentially fibres with a diameter of about 23 nm (type I) were produced. When elemental sulfur was substituted by thiosulfate fibers with a diameter of around 15 nm (type II), were the main appendages. Both types form hollow cylinders consisting of helically arranged sub-units with a wall thickness of 2–3 nm. A triple- layered unit membrane could not be found. |
