ABSTRACT
A strictly aerobic Gram-stain-positive bacterial strain, designated IB-3T, was isolated from a car air-conditioning system in the Republic of Korea. Cells were non-motile rods showing catalase- and oxidase-positive reactions. Growth of IB-3T was observed at 20-40 °C (optimum, 25 °C), at pH 6.5-9.0 (optimum, pH 7.5) and in the presence of 0-1â% (w/v) NaCl (optimum, 0â%). Menaquinone-8 (H4) was detected as the predominant respiratory quinone and iso-C16ââ0, 10-methyl-C17ââ0, iso-C17ââ0, C18ââ1ω9c, C17ââ1ω8c, C18ââ0, 10-methyl-C18ââ0 (TBSA) and C17ââ0 were identified as the major cellular fatty acids. Phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and phosphatidylinositol were detected as the major polar lipids. The major cell wall peptidoglycan type was ll-2,6-diaminopimelic acid. The G+C content of the genomic DNA was 71.5 mol%. IB-3T was most closely related to Nocardioides terrigenaDS-17T with a 98.0â% 16S rRNA gene sequence similarity. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that IB-3T formed a distinct phylogenetic lineage within the genus Nocardioidesof the family Nocardioidaceae. On the basis of the phenotypic, chemotaxonomic and molecular features, IB-3T represents a novel species of the genus Nocardioides, for which the name Nocardioidescurrus sp. nov. is proposed. The type strain is IB-3T (=KACC 19522T=JCM 32672T).
