Comparisons of 16S rRNA gene sequences showed that the three strains were very closely related to each other (sequence similarities of 99.6–99.8 %). A polyphasic taxonomic study of the isolates resulted in their identification as members of the genus Chryseobacterium (family Flavobacteriaceae, phylum Bacteroidetes). The three strains showed ≤96.9 % sequence similarity with respect to the type strains of described Chryseobacterium species, indicating that H9T, H10 and H15 represent a novel species of the genus Chryseobacterium. The three strains grew at 7–37 °C (strain H10 grew at up to 41 °C), with 0–2.5 % NaCl and at pH 5.0–9.8. The dominant cellular fatty acids of strain H9T were 15 : 0 iso (38.9 %), 15 : 0 anteiso (15.6 %) and 17 : 0 iso 3-OH (12.7 %). Strain H10 also possessed 17 : 1 iso ω9c (14.8 %) as a major fatty acid. On the basis of phenotypic properties and phylogenetic distinctiveness, the three milk isolates represent a novel species in the genus Chryseobacterium, for which the name Chryseobacterium bovis sp. nov. is proposed. The type strain is H9T (=LMG 24227T =DSM 19482T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.65500-0
