Luteococcus sediminum sp nov., isolated from deep subseafloor sediment of the South Pacific Gyre

A Gram-stain-positive, strictly aerobic, coccus-shaped, non-motile, yellow-pigmented bacterium, designated strain XH208(T), was isolated from a deep subseafloor sediment sample collected from the South Pacific Gyre (41 degrees 58' S 163 degrees 11' W) during the Integrated Ocean Drilling Program (IODP) Expedition 329. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain XH208(T) belonged to the genus Luteococcus and showed the highest 16S rRNA gene sequence similarities with Luteococcus peritonei CCUG 38120(T) (96.9%), Luteococcus japonicus DSM 10546(T) (95.4%) and Luteococcus sanguinis CCUG 33897(T) (95.2%). The DNA G +C content of strain XH208(T). was 66.9 mol%. The cell wall of strain XH208(T) possessed a type A3y peptidoglycan (LL-diaminopimelic acid glycine), and ribose, glucose and galactose as the major whole-cell sugars. The major fatty acids were C-17:1 omega 8c, C-17:1 omega 6c, and C-16:1 omega 6C and/or C-16:1 omega 7c (summed feature 3). The major respiratory quinone was menaquinone MK-9(F-14). The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol and phosphatidylinositol. On the basis of data from the polyphasic analysis, strain XH208(T) is considered to represent a novel species in the genus Luteococcus, for which the name Luteococcus sediminum sp. nov. is proposed. The type strain is XH208(T) (=DSM 27277(T)=JCM 19259(T)).
