Cells of the organism were Gram-positive, catalase-positive, oxidase-negative and non-motile rods. The organism contained LL -diaminopimelic acid in the cell-wall peptidoglycan and MK-8(H 4 ) as predominant menaquinone, and had a polar lipid profile containing phosphatidylglycerol and phosphatidylinositol, iso-C 16 : 0 as the major fatty acid and a DNA G+C content of 73.1 mol%. A neighbour-joining tree based on 16S rRNA gene sequences showed that the organism occupies a distinct phylogenetic position within the radiation including representatives of the family Nocardioidaceae . High levels of 16S rRNA gene sequence similarity were found with Nocardioides kribbensis (97.2 %), Nocardioides aquiterrae (96.9 %), Nocardioides pyridinolyticus (96.6 %) and Nocardioides aquaticus (96.3 %). The combination of morphological and chemotaxonomic characteristics was consistent with classification in the genus Nocardioides , but the isolate can be differentiated from all Nocardioides species with validly published names by a range of physiological properties. The name Nocardioides marinisabuli sp. nov. is proposed for this novel organism, with the type strain SBS-12 T (=JBRI 2003 T =KCCM 42681 T =DSM 18965 T ). The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain SBS-12 T is AM422448 .
