A novel actinobacterial strain, B2-12T, was isolated from soil of a crater lake, Baekrokdam, Hallasan, Jeju, Republic of Korea. Cells of strain B2-12Twere Gram-stain-positive, non-motile, non-spore-forming and coccoid to short-rod-shaped. Phylogenetic analysis, based on 16S rRNA gene sequencing, showed that strain B2-12Tbelonged to the genus Nocardioides and shared highest sequence similarity with ‘Nocardioidespaucivorans’ KIS31-44 (98.4%). The predominant isoprenoid quinone was MK-8(H4). The major fatty acids of strain B2-12T were C16:1(ω7c and/or ω6c), summed feature 9 (iso-C17:1ω9c and/or C16:010-methyl), C17:010-methyl, iso-C16:0, C16:0and C17:1ω6c. The diagnostic diamino acid in the cell-wall peptidoglycan was ll-diaminopimelic acid. It contained diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol as the polar lipids. The DNA G+C content was 67.0 mol%. Based on phylogenetic, chemotaxonomic and phenotypic data, 16S rRNA gene sequence comparisons and DNA-DNA hybridization data, strain B2-12Trepresents a novel species in the genus Nocardioides, for which the name Nocardioidesbaekrokdamisolisp. nov. is proposed. The type strain is B2-12T(=KCTC 39748T=NRRL B-65313T=DSM 100725T).
