Abstract
|
|
|
|
The genus Idiomarina belongs to the class Altermonadales has been known as a Gram-stain-negative and halophile. Also, the members of the genus Idiomarina as an aerobic heterotroph have little understanding of their abilities in nature. The present study isolated strain MSP-CT from the marine sediment and analyzed its single complete genome sequence. The circularizedcomplete genome size and G + C content were about 2.61 Mb and 47.1%, respectively. The single chromosome encoded 2,425 coding sequences with protein, 12 ribosomal RNA, and 56 transfer RNA genes. Strain MSP-CT genome encoded genes for biosynthesis for various vitamins, partial denitrification, and phosphorus uptake. Also, the genome harbored cbb3 and bd oxidases as a high affinity for oxygen under low-oxygen conditions. Taken together, strain MSP-CT might contribute to nutrient cycling and have a resistance against environmental stress in marine sediment.
