Abstract

A Gram-negative, rod-shaped, oxidase-positive, aerobic, non-motile and orange-pigmented bacterial strain, containing flexirubin-type pigments, designated H8T, was isolated from raw cow's milk in Israel. 16S rRNA gene sequence analysis indicated that the isolate should be placed in the genus Chryseobacterium (family Flavobacteriaceae, phylum Bacteroidetes). The levels of 16S rRNA gene sequence similarity between strain H8T and the type strains of described Chryseobacterium species were 97.5% or lower. Strain H8T grew at 5-37 °C and with 0-3.0% NaCl. The dominant cellular fatty acids were iso-15:0, iso-17:0 3-OH, iso-17:1ω9c and summed feature 3 (comprising iso-15:0 2-OH and/or 16:1ω7c). On the basis of phenotypic properties and phylogenetic distinctiveness, the milk isolate H8T is classified as a member of a novel species in the genus Chryseobacterium, for which the name Chryseobacterium oranimense sp. nov. (type strain H8T =5LMG 24030T =DSM 19055T) is proposed.
