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.

假单胞菌_ 菌株 DNDY-54 是一种反硝化细菌，是从印度洋九十东海脊的深海沉积物样本中分离出来的。在这里，我们显示 DNDY-54 的完整基因组有一个 4,412,895 bp 的环状染色体，平均 60.57% GC 含量。完整的基因组包含 4111 个预测的蛋白质编码基因、59 个 tRNA 和 4 个 rRNA 操纵子 16S-23S-5S rRNA。在注释结果的基础上，我们确定了编码 27 种与氮代谢相关的蛋白质的基因，包括构成完整反硝化途径的酶。这项工作将提高对深层生物圈中氮循环的理解，并为环境保护和废水处理应用提供新的候选者。
