Species
Shewanella loihica
Description and significance
PV-4T marine bacterial strain of Shewanella loihica was isolated at the deep-sea, hydrothermal Naha Vent from iron-rich microbial mats on the South Rift of Loihi Seamount, Hawaii, in the Pacific Ocean. It is noted as orange and rodlike with a mean length of 1.8 µm and a mean width of 0.7 µm. They are psychrotolerant at temperatures between 0-42 degrees C.

Genome structure
The loihica genome is recorded at having 4602594 nucleotides, 3859 protein genes, and 124 RNA genes. (Kegg Encyclopedia. 1 May 2007 <http://www.genome.jp/kegg-bin/show_organism?org=slo>) PV-4(T) exhibited 16S rRNA gene sequence similarity levels of 99.6% to Shewanella aquimarina, 97.5 % to S. marisflavi, 50.5 % to S. aquimarina and 8.5 % to S. marisflavi.
Cell structure and metabolism
The S. loihica is noted as being gram-negative and motile through polar flagella.
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
"They are capable of using a variety of compounds as electron acceptors, including oxygen, iron, manganese, uranium, nitrate, nitrite, fumarate, to name a few. This ability makes Shewanella important for bioremediation of contaminated metals and radioactive wastes."
