  • Title: Nocardioides marinisabuli sp. nov., a novel actinobacterium isolated from beach sand.
    Author: Lee DW, Hyun CG, Lee SD.
    Journal: Int J Syst Evol Microbiol; 2007 Dec; 57(Pt 12):2960-2963. PubMed ID: 18048757.
    Abstract:
    The taxonomic position of a novel actinobacterium (designated SBS-12(T)), which was isolated from beach sand on Jeju Island, Republic of Korea, was determined following a polyphasic taxonomic characterization. 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)).
