Three Gram-stain-negative, strictly aerobic, rod-shaped with single polar flagellum, yellow-pigmented bacteria, designated strains XH031(T), XH038-3 and XH80-1, were isolated from deep-sea sediment of the South Pacific Gyre (41° 51' S 153° 6' W) during the Integrated Ocean Drilling Program (IODP) Expedition 329. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolates belonged to the genus Luteimonas and showed the highest 16S rRNA gene sequence similarity with Luteimonas aestuarii B9(T) (96.95%), Luteimonas huabeiensis HB2(T) (96.93%) and Xanthomonas cucurbitae LMG 690(T) (96.92 %). The DNA G+C contents of the three isolates were 70.2-73.9 mol%. The major fatty acids were iso-C(15 : 0), iso-C(16 : 0), iso-C(11 : 0) and C16 : 010-methyl and/or iso-C(17 : 1)ω9c. The major respiratory quinone was ubiquinone-8 (Q-8). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and one unknown phospholipid. On the basis of data from polyphasic analysis, the three isolates represent a novel species of the genus Luteimonas, for which the name Luteimonas abyssi sp. nov. is proposed. The type strain is XH031(T) ( = DSM 25880(T) = CGMCC 1.12611(T)).
三株革兰氏阴性、严格需氧、杆状、单极鞭毛、黄色素产生菌，菌株 XH031(T)、XH038-3 和 XH80-1，是在综合大洋钻探计划（IODP）第 329 航次期间，从南太平洋 Gyre（41°51'S 153°6'W）深海沉积物中分离得到的。基于 16S rRNA 基因序列的系统发育分析表明，这些分离物属于 Luteimonas 属，与 Luteimonas aestuarii B9(T)（96.95%）、Luteimonas huabeiensis HB2(T)（96.93%）和 Xanthomonas cucurbitae LMG 690(T)（96.92%）的 16S rRNA 基因序列相似度最高。三株菌的 DNA G+C 含量为 70.2-73.9mol%。主要脂肪酸为 iso-C(15:0)、iso-C(16:0)、iso-C(11:0)和 C16:010-methyl 和/或 iso-C(17:1)ω9c。主要呼吸醌为 ubiquinone-8 (Q-8)。主要极性脂为磷脂酰乙醇胺、磷脂酰甘油、双磷脂酰甘油和一种未知磷脂。基于多相分析数据，这三株菌代表了 Luteimonas 属的一个新种，命名为 Luteimonas abyssi sp. nov.。模式菌株为 XH031(T)（=DSM 25880(T)=CGMCC 1.12611(T)）。
