''Geothermobacter ehrlichii'' is a Gram negative bacterium. It is shaped like a rod and is 1.2 to 1.5 µm in length and 0.5 µm in diameter. It does not form spores.

Description and Significance
Geothermobacter ehrlichii is a Gram negative bacterium. It is shaped like a rod and is 1.2 to 1.5 µm in length and 0.5 µm in diameter. It does not form spores. This microorganism expresses a flagellum up to 6 µm long allowing it to be very motile. It also has pili all along its outer surface which are thought to aid it in biofilm interactions [1]. Geothermobacter literally means “a rod from hot earth” which seems to perfectly describe this microorganism for its capacity to live in temperatures up to 65°C. Geothermobacter ehrlichii was isolated from a hydrothermal chimney named Bag City. It is a strict anaerobe and its main metabolic process is reduction of Fe(III).
Genome Structure
The complete genome sequence of this novel bacterium is not yet available so very little is known about the size and content of the genome. Most of what is known about the DNA sequence of this bacterium is from isolated strain SS015 [2]. It has a 62.6% G+C content and phylogenetic analysis of its 16S rRNA has shown that it is most similar to other members of the family Geobacteraceae. Other interesting facts include resistance to antibiotics like trimethoprim and tetracycline.
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
