Abstract

Genus Microbulbifer plays important roles in element cycling process in marine environments, and the first type strain KCTC 12973^T (=ISL-39^T = CCUG 54356^T) of M. celer was isolated and identified in 2007. However, the genome sequence of M. celer KCTC 12973^T is still unclear, which complicates the functional exploration and new species identification of other species belonged to this genus. This study reported the complete genome sequence of M. celer KCTC 12973^T with a genome size of 4,346,001 bp. A total of 3601 protein-coding genes were annotated in the genome. The potential genes involved in the polysaccharide degradation, including cellulose, chitin, xylan, and pectate, were found in the protein-coding genes. Besides, the reductase genes of nitrate and nitrite were also annotated in the genome. These findings indicated the potential crucial ecological functions of M. celer KCTC 12973^T for carbon and nitrogen cycles in marine ecosystems.

具有多个多糖降解基因的模式菌株——微球藻KCTC12973T的第一个完整基因组序列。

微球菌属(Microbulbifer)在海洋环境元素循环过程中起着重要作用，2007年分离鉴定了M. celer的第一个类型菌株KCTC 12973T (= is - 39t = CCUG 54356T)。然而，M. celer KCTC 12973T的基因组序列尚不清楚，这给该属其他物种的功能探索和新种鉴定带来了困难。本研究报道了M. celer KCTC 12973T的全基因组序列，基因组大小为4,346,001 bp。基因组中共注释了3601个蛋白质编码基因。在蛋白质编码基因中发现了参与多糖降解的潜在基因，包括纤维素、几丁质、木聚糖和果胶酸。此外，硝酸盐和亚硝酸盐还原酶基因也在基因组中被注释。这些结果表明M. celer KCTC 12973T对海洋生态系统碳氮循环具有潜在的关键生态功能。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
