Query: NC_009092:1684467 Shewanella loihica PV-4, complete genome Lineage: Shewanella loihica; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria General Information: This strain is an environmental isolate from the Naha Vents, Hawaii, in the Pacific Ocean. Psychrotolerant bacterium. This genus includes species that inhabit a wide range of environments and are capable of utilizing a wide variety of electron acceptors during anaerobic respiration including some insoluble metal oxides while using very few carbon sources such as lactate or acetate. This group of organisms have been studied extensively for their electron transport systems. Shewanella loihica is a psychrotolerant deep sea bacterium. This organism is able to reduce iron, manganese and uranium and may be useful for bioremediation at low temperatures.

General Information: This is the type strain for this organism, which was isolated from a hydrothermal vent at a depth of 1300 m from the Lo'ihi Seamount southeast of Hawaii. This organism grows optimally in salt concentrations of 7.5 to 10%. Genome comparison has suggested that the bacterium has maintained its amino acid transport and degradation systems but lost sugar transport and certain sugar metabolic genes suggesting that it lives on amino acids rather than sugars. This may be in keeping with the environment this organism grows in, which is at hydrothermal deep sea vents that are characterized by collections of proteinaceous particles. This organism may colonize these particles by producing exopolysaccharides.
