Query: NC_009901:1693500 Shewanella pealeana ATCC 700345, complete genome
Lineage: Shewanella pealeana; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This species was isolated from a microbial community colonizing the accessory nidamental gland of the squid Loligo peali (Atlantic squid) for their capacity to respire on sulfur. It was placed in the Shewanella genus based on physiological and biochemical characteristics and 16S rRNA sequence analysis. Shewanella are ubiquitous in marine environment and play very important role in global carbon and nitrogen cycle. The present strain is moderately halophilic, requiring sodium ions for growth. Shewanella are facultatively anaerobic, Gram-negative bacteria, motile by polar flagella, rod-like, and generally associated with aquatic or marine environments.
Subject: NC_006512:551312 Idiomarina loihiensis L2TR, complete genome
Lineage: Idiomarina loihiensis; Idiomarina; Idiomarinaceae; Alteromonadales; Proteobacteria; Bacteria
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.
