Abstract
|
|
|
|
The complete whole genome sequences were obtained from a bacterial strain M13 isolated from the intestine of Dokdo shrimp, Lebbeus groenlandicus caught in the East Sea, near Ulleung island, South Korea. The strain was isolated at a low temperature (4°C) similar to those of the sea environment, where its host lived. Phylogenetic analysis showed that the strain contained 16S rRNA gene similarities lower than 98.55% of the species of genus Psychrobacter in the family Moraxellaceae. Whole genome sequencing using the PacBio RS II system yielded two circular contigs (a chromosome and a plasmid of 3,177,391 and 29,784 bp with G + C contents of 42.6 and 40.7 mol %, respectively). The genome has a total of 2,712 genes coding 2,654 CDSs, 46 tRNAs, 8 rRNAs, and 4 ncRNAs as well as an incomplete prophage region and a potential gene cluster for production of secondary metabolites. The genome also contains four genes coding cold-shock proteins that make bacteria adapt to cold temperatures.
