Nocardioides currus sp. nov., isolated from a mobile car air-conditioning system. Int J Syst Evol Microbiol. 2018 Jul 20;: Authors: Park YJ, Jeong SE, Jung HS, Park SY, Jeon CO 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 0-1 % (w/v) NaCl (optimum, 0 %). Menaquinone-8 (H4) was detected as the predominant respiratory quinone and iso-C16 : 0, 10-methyl-C17 : 0, iso-C17 : 0, C18 : 1ω9c, C17 : 1ω8c, C18 : 0, 10-methyl-C18 : 0 (TBSA) and C17 : 0 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 98.0 % 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 m...
