Complete Genome Sequence of Oceanimonas sp. GH1

May 4, 2012

The Gram-negative, rod-shaped Oceanimonas sp. GK1, isolated from Gavkhouni Wetland in Iran, belongs to the Aeromonadaceae family. It is a motile aerobic bacterium which can tolerate up to 12% NaCl, grows at 10 to 45°C (optimum, 35°C) and pH 6 to 10 (optimum, 8), and produces large amounts of poly-β-hydroxybutyrate (PHB) as a carbon and energy reservoir under unbalanced growth conditions. PHB is a biodegradable and renewable biosynthetic polymer which can be used in medicine, tissue engineering, and packaging materials. Despite these features the Oceanimonas species are relatively poorly characterized in terms of genetic and genome characteristics. The whole genome sequence of this strain is the first report of a completely sequenced and annotated genome from the Oceanimonas genus.

The whole-genome sequencing resulted in a single circular chromosome of 3,514,537 bp and two plasmids 8,462 and 4,245 bp in length. The complete Oceanimonas sp. GK1 genome has been deposited in GenBank under the accession no.CP003171 for the chromosome and CP003172 and CP003173 for the two plasmids. The genome project data are also available at GenBank under the Genome Project identification number (ID) 68171.
