Is pyrococcus Furiosus prokaryotic or eukaryotic?
Pyrococcus furiosus is an extremophilic species of Archaea. It can be classified as a hyperthermophile because it thrives best under extremely high temperatures—higher than those preferred of a thermophile….

Is pyrococcus Furiosus anaerobic?
It is anaerobic and heterotrophic in nature and has a fermentative metabolism. The P. furiosus is found in deep sea vents and volcanic marine mud off of Italy, and can be cultured in its genus specific Pyrococcus complex medium that contains salts, yeast extract, peptone, sulfur, seawater, and a few other components.
What is the shape of Pyrococcus furiosus?
Cell Structure and Metabolism Image of P. furiosus. Courtesy of Henry Aldrich. The cells of Pyrococcus are about 0.8- 2um and are slightly irregular cocci in shape.
What is the characteristics of Pyrococcus furiosus?
Pyrococcus furiosus (“rushing fireball”) was named for the ability of this archaeal coccus to rapidly swim at its optimal growth temperature, around 100°C. Early electron microscopic studies identified up to 50 cell surface appendages originating from one pole of the coccus, which have been called flagella.
What does the Pyrococcus furiosus eat?
University of Georgia researchers recently used the mighty Pyrococcus furiosus, which usually eats carbohydrates and lives in super-heated waters or volcanic marine mud (ideally, for it, at about 100 degrees Celsius).
Where can pyrococcus Furiosus be found?
Pyrococcus furiosus is a hyperthermophilic archaea obtained from geothermally heated marine sediments in Italy and grows optimally at 100 ° C (Fiala and Stetter, 1986).

Is Pyrococcus gram negative?
How are the flagella of Pyrococcus furiosus acquired?
And, at least 100 ORFs have been acquired through lateral gene transfer (12). P. furiosus has flagella that are attached to one pole of the cell. It is composed of mainly one type of glycoprotein similar to bacterial flagellin, but differs in other aspects from bacterial flagella.
What makes Pyrococcus furiosus unique among hyperthermophiles?
Moreover, it is unique among its kind in that it can use a wide range of compounds as a carbon source, such as peptides and carbohydrates (14). And unlike other hyperthermophiles, it does not need elemental sulfur for growth (7). P. furiosus is a single circular chromosome organism.
How many composite transposons does Pyrococcus furiosus have?
In its genome, P. furiosus has up to 28 composite transposons, allowing for the DNA to be mobilized to other chromosomes, allowing genetic exchanges in this vent that may have lead to the divergence of other species in the vent (14).
How long does it take Pyrococcus furiosus to grow?
Since it is a hyperthermophile, it is actually crippling to these organisms to be at the lower to moderate range of temperature. When the temperate of a culture of P. furiosus is dropped from 95 0C to 72 0C, there was a 5 hours lag in its growth phase.
