Abstract
- Two bacterial strains designated as W3-2-3 <superscript>T</superscript> and HKS04 <superscript>T</superscript> were isolated from mineral water and a soil sample, respectively, in the Republic of Korea. The 16S rRNA genes of the two strains shared a sequence similarity of 93.5 %. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains W3-2-3 <superscript>T</superscript> and HKS04 <superscript>T</superscript> formed a distinct lineage within the genus Nocardioides of the family Nocardioidaceae (order Propionibacteriales ). The closely related species of strain W3-2-3 <superscript>T</superscript> were Nocardioides albidus (98.9 %), Nocardioides caeni (98.8 %), Nocardioides kongjuensis (98.6 %), Nocardioides aromaticivorans (98.5 %), Nocardioides nitrophenolicus (98.4 %), Nocardioides flava (98.2 %) and Nocardioides ginsengisoli (98.1 %). The closest species of strain HKS04 <superscript>T</superscript> was Nocardioides halotolerans (98.7 %). The genome sizes of strains W3-2-3 <superscript>T</superscript> and HKS04 <superscript>T</superscript> were 4741198 and 5 120341 bp, respectively. The genomic DNA G+C contents of strains W3-2-3 <superscript>T</superscript> and HKS04 <superscript>T</superscript> were 73.3 and 72.1 mol%, respectively. The main fatty acids of strain W3-2-3 <superscript>T</superscript> were C <subscript>17:1</subscript> ω 6 c and iso-C <subscript>16:0</subscript> and those of strain HKS04 <superscript>T</superscript> were iso-C <subscript>16:0</subscript> and iso-C <subscript>16:0</subscript> H. The main polar lipids of both strains were diphosphatidylglycerol and phosphatidylglycerol and the predominant respiratory quinone was MK-8(H <subscript>4</subscript> ), supporting the affiliation of these strains with the genus Nocardioides . Based on the results of biochemical, chemotaxonomic and phylogenetic analyses, two novel species, Nocardioides convexus W3-2-3 <superscript>T</superscript> (KACC 21211 <superscript>T</superscript> =LMG 31251 <superscript>T</superscript> ) and Nocardioides anomalus HKS04 <superscript>T</superscript> (KACC 18879 <superscript>T</superscript> =LMG 31249 <superscript>T</superscript> ), are proposed.
