The marine bacterium Neptunomonas concharum was firstly characterized in 2012. It preferred to utilize acetate as the carbon source to accumulate poly-3-hydroxybutyrate (PHB) as intracellular carbon and energy storage. Here we report the genomic characteristics of N. concharum JCM17730^T. The complete genome sequence of N. concharum JCM17730^T consists of 3,561,992 bp in one contig, without plasmid. Analysis of coding sequences revealed the presence of genomic features involved in acetate assimilation and PHB metabolism. The genome of N. concharum JCM17730^T contains three genes encoding acetyl-CoA synthetase and two genes encoding isocitrate lyase. Three polyhydroxyalkanoate synthases and one polyhydroxyalkanoate depolymerase are scattered throughout the genomic DNA. The genome features provide interesting insights into the acetate and PHB metabolism of N. concharum JCM17730^T and would facilitate further research on the genetic engineering of marine bacteria for efficient PHB production.

海洋细菌炭疽菌（Neptunomonas concharum）的首次特征是在2012年。它优选利用乙酸盐作为碳源来积累聚3-羟基丁酸酯（PHB）作为细胞内的碳和能量存储。在这里，我们报告N. concharum JCM17730 ^T的基因组特征。炭疽烟草JCM17730 ^T的完整基因组序列由一个重叠群中的3,561,992 bp组成，无质粒。编码序列的分析揭示了参与乙酸同化和PHB代谢的基因组特征的存在。炭疽杆菌JCM17730 ^T的基因组含有三个编码乙酰辅酶A合成酶的基因和两个编码异柠檬酸裂合酶的基因。三种聚羟基链烷酸合酶和一种聚羟基链烷酸解聚酶分散在整个基因组DNA中。基因组特征为炭黑猪笼草JCM17730 ^T的乙酸盐和PHB代谢提供了有趣的见识，并将有助于进一步研究海洋细菌的基因工程以有效生产PHB。
