title: Luteimonas abyssi sp. nov., isolated from deep-sea sediment.
abstract: 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)).
