Phylogenetic analysis based on 16S rRNA gene sequences revealed that this isolate had less than 97·0 % similarity to any Rhodococcus species with validly published names, with the exception of Rhodococcus fascians (DSM 20669T), which was found to be its closest neighbour (98·9 % similarity). Chemotaxonomic data, including peptidoglycan type, diagnostic sugar compositions, fatty acid profiles, menaquinones, polar lipids and mycolic acids, were determined for this isolate; the results supported the affiliation of strain YIM 70056T to the genus Rhodococcus. The DNA G+C content was 63·5 mol%. The results of DNA–DNA hybridization with R. fascians DSM 20669T, in combination with chemotaxonomic and physiological data, demonstrated that isolate YIM 70056T represents a novel Rhodococcus species, for which the name Rhodococcus yunnanensis sp. nov. is proposed, with YIM 70056T (=CCTCC AA 204007T=KCTC 19021T=DSM 44837T) as the type strain., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.63390-0
