A yellow-pigmented novel bacterial strain, MAH-12T, was isolated from a soil sample of Korean radish garden and was characterized using a polyphasic approach. Cells were Gram-staining negative, non-motile and rod-shaped. The strain was aerobic, catalase positive, optimum growth temperature and pH were 28–30 °C and 6.0, respectively. The novel strain is able to hydrolyze l-tyrosine, starch, esculin and 4-nitrophenyl-β- d-galactopyranoside. On the basis of 16S rRNA gene sequence analysis, strain MAH-12T belongs to the genus Sphingobium and is most closely related to several Sphingobium type strains (97.2–97.8%). In DNA–DNA hybridization tests, the DNA relatedness between strain MAH-12T and its closest phylogenetic neighbors was below 45.0%. The DNA G + C content was 64.0 mol% and the predominant respiratory quinone was ubiquinone-10. The major cellular fatty acids were summed feature 8 (C18:1 ω7c and/or C18:1 ω6c) and C16:0. The DNA–DNA hybridization results and results of the genotypic analysis in combination with chemotaxonomic and physiological data demonstrated that strain MAH-12T represented a novel species within the genus Sphingobium, for which the name Sphingobium tyrosinilyticum is proposed. The type strain is MAH-12T (= KACC 19297T = CGMCC 1.16225T). The NCBI GenBank accession number for the 16S rRNA gene sequence of strain MAH-12T is KY964278 and the digital protologue database taxon number of strain MAH-12T is TA00463.
