Three Gram-negative, non-motile, non-spore-forming short rods (strains PB56^T, PB180, PB229) were isolated from soil in South Korea. Cells were orange–red in colour. Strains PB180 and PB229 contained small amounts of bacteriochlorophyll a, which was not detected in strain PB56^T. However, all three isolates contained the genes for the photosynthetic type II reaction centre, pufLM. They contained Q-10 as the dominant quinone and C_{18 : 1} as the dominant fatty acid. The highest 16S rRNA gene sequence similarities were found to Sphingomonas oligophenolica JCM 12082^T (95.8 %), Sphingomonas koreensis KCTC 2882^T (95.1 %), Sphingomonas mali IFO 15500^T (95.1 %), Sphingomonas faeni DSM 14747^T (94.8 %), Sphingomonas pruni IFO 15498^T (94.7 %) and Sphingomonas aquatilis KCTC 2881^T (94.6 %), as well as to Sphingosinicella microcystinivorans Y2^T and Sphingosinicella xenopeptidilytica 3-2W4^T (95.0–95.2 %). Phylogenetic analyses supported the assignment of strains PB56^T, 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 PB56^T (=KCTC 12334^T=DSM 16846^T).

The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains PB56^T, PB180 and PB229 are respectively AY769083, AY769084 and AY785128.

Details of the analysis of the carotenoids of the novel strains are available in a supplementary figure and table with the online version of this paper.
