Cells were orange–red in colour. Strains PB180 and PB229 contained small amounts of bacteriochlorophyll a, which was not detected in strain PB56T. However, all three isolates contained the genes for the photosynthetic type II reaction centre, pufLM. They contained Q-10 as the dominant quinone and C18 : 1 as the dominant fatty acid. The highest 16S rRNA gene sequence similarities were found to Sphingomonas oligophenolica JCM 12082T (95.8 %), Sphingomonas koreensis KCTC 2882T (95.1 %), Sphingomonas mali IFO 15500T (95.1 %), Sphingomonas faeni DSM 14747T (94.8 %), Sphingomonas pruni IFO 15498T (94.7 %) and Sphingomonas aquatilis KCTC 2881T (94.6 %), as well as to Sphingosinicella microcystinivorans Y2T and Sphingosinicella xenopeptidilytica 3-2W4T (95.0–95.2 %). Phylogenetic analyses supported the assignment of strains PB56T, PB180, PB229 to the genus Sphingomonas. The novel isolates differ from all established species of the genus Sphingomonas by their higher G+C content and the absence of straight-chain 2-hydroxy fatty acids. Based on the phylogenetic distances from species with validly published names and their phenotypic properties, the strains constitute a separate species, for which the name Sphingomonas kaistensis sp. nov. is proposed. The type strain is PB56T (=KCTC 12334T=DSM 16846T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.64579-0
