Abstract

Yellow-pigmented, Gram-negative organisms isolated from raw chicken were investigated by means of a polyphasic taxonomic approach and were shown to represent a novel species in the genus Chryseobacterium, for which the name Chryseobacterium vrystaatense sp. nov. is proposed. Its nearest phylogenetic neighbours were Chryseobacterium joostei, Chryseobacterium indologenes and Chryseobacterium gleum, which showed 16S rRNA gene sequence similarity levels of 96·9, 97·1 and 96·1 %, respectively. Levels of DNA–DNA hybridization between strains of C. vrystaatense and Chryseobacterium reference species were below 46 %. Strain LMG 22846T (=CCUG 50970T) was chosen as the type strain and has a DNA G+C content of 37·1 mol%.
