Pyrobacterium abyssi (Species)

Description and Significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

Genome Structure

The genome has not yet been sequenced, but using relationships between various hyperthermophiles with respect to their size, their structural organization and their phylogenetic relationship based on the content of the respectetive 16rDNA genes it is determined the entire genome of pyrodictium abyssi is a single circular chromosome and approximately 1.6Mb. It is very similar to Hyperthermus butylicus (97% sequence coverage) and pyrodicium occultum (96% sequence coverage), which is another sulfur reducing hyperthermophile belonging to the same genus both with E-values of 0.

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.
