Strain R1-1\n T<\/jats:sup>\n grew at 20\u201345 \u2103, pH 4.0\u201311.0 and 0\u201310%\u2009NaCl. Notably, this strain degraded 50\u2009mg l\n \u22121<\/jats:sup>\n pymetrozine within 18\u2009h at pH 8.0. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain R1-1\n T<\/jats:sup>\n belongs to the genus\n Nocardioides<\/jats:italic>\n , showing a high sequence similarity to \u2018\n Nocardioides carbamazepini<\/jats:italic>\n \u2019 CBZ-1\n T<\/jats:sup>\n (98.5%). Other closely related species included\n Nocardioides albidus<\/jats:italic>\n THG-S11.7\n T<\/jats:sup>\n (98.0%),\n Nocardioides convexus<\/jats:italic>\n W3-2-3\n T<\/jats:sup>\n (98.0%),\n Nocardioides kongjuensis<\/jats:italic>\n A2-4\n T<\/jats:sup>\n (98.0%) and\n Nocardioides daeguensis<\/jats:italic>\n JCM 17460\n T<\/jats:sup>\n (97.4%). The genome sequence of strain R1-1\n T<\/jats:sup>\n had a G+C content of 72.2 mol%. The average nucleotide identity and DNA\u2013DNA hybridization values between strain R1-1\n T<\/jats:sup>\n and its closest phylogenetic relatives were 84.5\u201384.9%\u2009and 28.5\u201328.7%, respectively. These values were below the determined thresholds for species delineation. The major fatty acids of strain R1-1\n T<\/jats:sup>\n were identified as 10-methyl C\n 18\u200a:\u200a0<\/jats:sub>\n , iso-C\n 16\u200a:\u200a0<\/jats:sub>\n and C\n 18\u200a:\u200a1<\/jats:sub>\n \u2009\u03c99c. The predominant respiratory quinone was menaquinone-8 (H\n 4<\/jats:sub>\n ), and the polar lipid profile comprised diphosphatidylglycerol, phosphatidylglycerol, two unidentified phospholipids and two unidentified lipids. Based on the polyphasic taxonomic data, strain R1-1\n T<\/jats:sup>\n represents a novel species within the genus\n Nocardioides<\/jats:italic>\n , for which the name\n Nocardioides pymetrozini<\/jats:italic>\n sp. nov. is proposed. The type strain is R1-1\n T<\/jats:sup>\n (=KCTC 59241\n T<\/jats:sup>\n =GDMCC 4.365\n T<\/jats:sup>\n ).\n
