“…Members within this genus have been isolated from various sources, such as different soil ecosystems (rhizosphere, desert, forest, farmland, etc.) [2][3][4][5], aquatic ecosystems (hot water spring and freshwater lake sediment) [6,7], plants [8][9][10], and animal faeces [11][12][13]. Some species in the genus Nocardioides such as Nocardioides sp.…”

A polyphasic taxonomic characterization of two novel strain pairs (designated zg-579T/zg-578 and zg-536T/zg-ZUI104) isolated from the faeces of Marmota himalayana was conducted based on phylogenetic analysis of the nearly full-length 16S rRNA gene and genome, digital DNA–DNA hybridization, ortho-average nucleotide identity (Ortho-ANI), and phenotypic and chemotaxonomic traits. Comparative analysis of the nearly full-length 16S rRNA gene sequences showed that strain zg-579T was most closely related to Nocardioides dokdonensis FR1436T (97.57 %) and Nocardioides deserti SC8A-24T (97.36 %), whereas strain zg-536T had the highest similarity to Nocardioides caeni MN8T (98.33 %), Nocardioides convexus W2-2-3T (98.26 %) and Nocardioides daeguensis 2C1-5T (98.19 %). Low levels of DNA–DNA relatedness and Ortho-ANI values (19.8–31.0 %/78.6–88.2 %, zg-579T; 19.9–31.3 %/78.8–86.2 %, zg-536T) between the two new type strains and previously known species within the genus Nocardioides support the hypothesis that the four newly characterized strains could be considered to represent two novel species within this genus. The dominant cellular fatty acids found in strain pair zg-536T/zg-ZUI104 were iso-C16 : 0 and C18 : 1 ω9c, whereas C17 : 1 ω8c was major component in zg-579T/zg-578. Galactose and ribose were the main cell-wall sugars in these two new strain pairs. Diphosphatidylglycerol (DPG), phosphatidylcholine, phosphatidylglycerol (PG) and phosphatidylinositol (PI) were the major polar lipids in zg-579T, whereas DPG, PG and PI predominated in zg-536T. Both strain pairs had MK8(H4) as the major respiratory quinone and ll-diaminopimelic acid as the major cell-wall peptidoglycan. The optimal growth conditions for the two novel strain pairs were 30 °C, pH 7.0 and 0.5 % NaCl (w/v). Based on these polyphasic characterizations, two novel species within the genus Nocardioides are proposed, i.e. Nocardioides marmotae sp. nov. and Nocardioides faecalis sp. nov., with zg-579T (=CGMCC 4.7663T=JCM 33892T) and zg-536T (=CGMCC 4.7662T=JCM 33891T) as the type strains.

A Gram-stain positive, facultatively anaerobic, non-motile and rod to coccoid-shaped bacterium, designated XZ17(T), was isolated from Namtso Lake of Tibet, China. Strain XZ17(T) grew optimally at pH 8.0-9.0, at 30-33 °C and in the presence of 0-1.0 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences demonstrated that strain XZ17(T) belongs to the genus Nocardioides in the family Nocardioidaceae. Strain XZ17(T) shared pairwise 16S rRNA gene sequence similarities of 97.2, 96.8, 96.5, 96.4 and <96.0 % to Nocardioides solisilvae KCTC 39528(T), Nocardioides daejeonensis JCM 16922(T), Nocardioides jensenii NCIB 9770(T), Nocardioides dubius KCTC 9992(T) and other Nocardioides species, respectively. It contained MK-8 (H4) as the predominant menaquinone and C17:1 ω8c, C15:0, C17:0 and C18:1 ω9c as the major fatty acid. The strain had cell wall peptidoglycan based on LL-2,6-diaminopimelic acid. The polar lipids of strain XZ17(T) comprised diphosphatidylglycerol, phosphatidylglycerol, three unidentified phospholipids, three unidentified glycolipids and two unidentified lipids. The DNA G+C content of strain XZ17(T) was 68.9 mol%. Based on distinctive phenotypic characteristics, phylogenetic analysis and chemotaxonomic data, it can be concluded that strain XZ17(T) represents a novel species within the genus Nocardioides, for which the name Nocardioides gilvus sp. nov. is proposed. The type strain is strain XZ17(T) (=KCTC 39561(T) = MCCC 1H00114(T)).
