Aeropyrum pernix
Description and significance
The Aeropyrum pernix is an aerobic archaeon and is spherical in shape with a diameter of about 1 micro meters. It grows optimally at pH 7.0 and at a temperature of 95 degrees celcius and a salinity of 3.5%. This archaeon is important enough to have its genome sequenced because it can help answer how the Aeropyrum pernix is able to consume oxygen in such an extreme environment. Only anaerobic Archaea was found in such living conditions, until the discovery of the Aeropyrum pernix. Aeropyrum pernix was isolated at a hydrothermal vent at kodakara island in Kagoshima Prefecture by a team of researchers at Kyoto University in 1993. The whole genome was sequenced by using the shotgun sequencing approach. Include a picture or two (with sources) if you can find them.
Genome structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Does it have any plasmids? Are they important to the organism's lifestyle?
