Complete genome sequence of the denitrifying Pseudomonas sp. strain DNDY-54 isolated from deep-sea sediment of ninety east ridge.

Pseudomonas sp. strain DNDY-54, a denitrifying bacterium, was isolated from a deep-sea sediment sample from Ninety East Ridge in the Indian Ocean. Here, we show that the complete genome of DNDY-54 has one circular chromosome of 4,412,895 bp with mean 60.57% GC content. The complete genome contains 4111 predicted protein-coding genes, 59 tRNAs, and 4 rRNA operons as 16S-23S-5S rRNA. On the basis of the annotation results, we identified genes that encode 27 proteins related to nitrogen metabolism, including enzymes that make up a complete denitrifying pathway. This work will improve the understanding of nitrogen cycling in the deep biosphere and provides a new candidate for protection of the environment and applications in waste water disposal.
