A novel proteobacterial bacterium, designated strain CAU 1489^T, was isolated from Jeju Island, Republic of Korea. Cells were strictly anaerobic, Gram stain-negative, cream-pigmented, non-spore-forming, motile and short rod-shaped. Strain CAU 1489^T exhibited the highest 16S rRNA gene sequence similarity (98.2%) to Nitratireductor mangrovi SY7^T. Multilocus sequence analysis of 16S rRNA and four housekeeping genes (rpoB, rpoC, gyrB and dnaK) indicated that CAU 1489^T represents a distinct branch within Nitratireductor. The whole genome was 4.8 Mb with a G + C content of 64.7 mol%, including protein-coding genes related to the function terms amino acids and derivatives, nucleotides and nucleosides, protein metabolism, carbohydrates and cofactors, vitamins, prosthetic groups and pigments. The major fatty acids were 11-methyl C_18:1ω7c, cyclo- C_19:0ω8c, iso-C_17:0 and summed feature 8 (C_18:1ω6c and/or C_18:1ω7c), and the predominant respiratory quinone was Q-10. The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and two unidentified phospholipids. Digital DNA–DNA hybridization and average nucleotide identity values were 19.4–22.0% and 72.4–79.1%, respectively. On the basis of taxonomic characterization, strain CAU 1489^T constitutes a novel species, for which the name Nitratireductor arenosus sp. nov. is proposed. The type strain is CAU 1489^T ( = KCTC 62997^T = NBRC 113694^T).

Nitratireductor arenosus sp。的多相分类学分析。十一月。，与海沙隔离。

一种新颖的变形杆菌细菌，指定应变CAU 1489 ^Ť，从济州岛，大韩民国隔离。细胞严格厌氧，革兰氏染色阴性，霜状色素，无孢子形成，能动和短杆状。菌株CAU 1489 ^T与硝酸还原酶mangrovi SY7 ^T表现出最高的16S rRNA基因序列相似性（98.2％）。16S rRNA和四个管家基因（rpo B，rpo C，gyr B和dna K）的多基因座序列分析表明，CAU 1489 ^T代表硝化还原酶内的一个独特分支。整个基因组为4.8 Mb，G + C含量为64.7 mol％，包括与功能术语氨基酸和衍生物，核苷酸和核苷，蛋白质代谢，碳水化合物和辅因子，维生素，辅基和色素有关的蛋白质编码基因。的主要脂肪酸为11-甲基Ç _18：1个ω 7 Ç，环Ç _19：0 ω 8 Ç，异-C _17：0和求和特征8（C _18：1个ω 6 ç和/或C _{18： 1和}ω 7 ç），主要的呼吸醌为Q-10。极性脂质包括二磷脂酰甘油，磷脂酰甘油，磷脂酰乙醇胺和两种未鉴定的磷脂。数字DNA–DNA杂交和平均核苷酸同一性值分别为19.4–22.0％和72.4–79.1％。根据分类学特征，菌株CAU 1489 ^T构成了一个新物种，其名称为Nitratireductor arenosus sp。十一月 被提议。类型应变为CAU 1489 ^T（= KCTC 62997 ^T  = NBRC 113694 ^T）。
