A Gram-negative, yellow-pigmented, rod-shaped bacterial strain YIM B02567 T was isolated from the root of Paris polyphylla Smith var. yunnanensis in China. Strain YIM B02567 T grew optimally at 25–30°C and at pH 7.0 in the absence of NaCl on nutrient agar. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain YIM B02567 T belong to the genus Chryseobacterium , and closely related to Chryseobacterium piperi CTM T and Chryseobacterium soli DSM 19298 T . Whole genome sequencing indicated that the genome size was 4,774,612 bp and had a DNA G+C content of 34.5 %. Values of the ANI and the dDDH between strain YIM B02567 T and its closely related Chryseobacterium species were below 81.72 % and 24.7 %. Strain YIM B02567 T contained menaquinone-6 as the sole isoprenoid quinone, anteiso-C 15:0, iso-C 17:1 ω 9 c and iso-C 17:0 3-OH as major fatty acids and phosphatidylethanolamine as major polar lipid. Based on the polyphasic analyses, strain YIM B02567 T could be differentiated genotypically and phenotypically from recognized species of the genus Chryseobacterium . The isolate therefore represents a novel species, for which the name Chryseobacterium paridis sp. nov. is proposed. The type strain is YIM B02567 T (=CGMCC 1.18657 T =JCM 5426 T ).
