Epulopiscium fishelsoni
Description and significance
Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated. Include a picture or two (with sources) if you can find them.
Epulopiscium was first discovered in 1985 by Lev Fishelson. He found them inside the intestines of a brown surgeonfish and was initially classified as a protist because of its large size. Epulopiscium fishelsoni was later discovered by Linn Montgomery and in 1993 Norman Pace performed an rRNA analysis which confirmed that it was actually a bacteria. At the time E. fishelsoni was the largest known bacteria, ranging from a length of ~30 to >600μm and a volume of >2,000-fold [2]. E. fishelsoni is a gram-positive bacterium that has an explicit symbiotic relationship with its surgeonfish hosts.
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?
Cell structure and metabolism
Describe any interesting features and/or cell structures; how it gains energy; what important molecules it produces.
Ecology
Describe any interactions with other organisms (included eukaryotes), contributions to the environment, effect on environment, etc.
Pathology
How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
Current Research
There are no ongoing/recent research being done about E. fishelsoni. After its discovery in 1985, thorough examinations of its structure and research about its reproduction process in the 90's, there is not much left that we don't know about this bacteria. There aren't any signs nor indications of future research projects for E. fishelsoni.
