The bacterial cells were Gram-negative, aerobic, short rods. The growth temperature and pH were 5–35 °C and 5.0–9.0, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that this isolate had 93.3–97.7 % similarity to Chryseobacterium species: the highest sequence similarities were to the type strains of Chryseobacterium daecheongense (97.7 %), Chryseobacterium formosense (97.1 %) and Chryseobacterium defluvii (96.9 %). Low levels of DNA–DNA relatedness were found between strain R2A10-2 T and the type strains of these three species (
