Description of Archaeoglobus fulgidus

Archaeoglobus fulgidus was the first sulphur-metabolizing organism to have its genome sequence determined. Growth by sulphate reduction is restricted to relatively few groups of prokaryotes; all but one of these are Eubacteria, the exception being the archaeal sulphate reducers in the Archaeoglobales. These organisms are unique in that they are only distantly related to other bacterial sulphate reducers, and because they grow at extremely high temperatures. The known Archaeoglobales are strict anaerobes, most of which are hyperthermophilic marine sulphate reducers found in hydrothermal environments. High-temperature sulphate reduction by Archaeoglobus species contributes to deep subsurface oil-well 'souring' by iron sulphide, which causes corrosion of iron and steel in oil-and gas-processing systems. Archaeoglobus fulgidus VC-16 is the type strain of the Archaeoglobales. Cells are irregular spheres with a glycoprotein envelope and monopolar flagella. Growth occurs between 60 and 95 degrees C, with optimum growth at 83 degrees C and a minimum division time of 4 hours. The organism grows organoheterotrophically using a variety of carbon and energy sources, but can grow lithoautotrophically on hydrogen, thiosulphate and carbon dioxide. We sequenced the genome of A. fulgidus strain VC-16 as an example of a sulphur-metabolizing organism and to gain further insight into the structure and content of archaeal genomes. The genome of A. fulgidus consists of a single, circular chromosome of 2,178,400 base pairs with a predicted total of 2,436 coding sequences.
