A Gram-staining-negative, rod-shaped, oxidase-positive, aerobic, non-motile and yellow-pigmented bacterial strain containing flexirubin type pigments, designated H1T, was isolated from raw cow's milk in Israel. 16S rRNA gene sequence analysis indicated that the isolate should be placed in the genus Epilithonimonas (family Flavobacteriaceae, phylum Bacteroidetes). The level of 16S rRNA gene sequence similarity between strain H1T and the type strain of Epilithonimonas tenax was 97.6 %. Strain H1T grew at 5-33 °C and with 0-2.0% NaCl. The dominant cellular fatty acids of strain H1 T were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (comprising iso-C15 : 0 2-OH and/or C 16 : 1ω7c), and the DNA G+C content was 38.0 mol%. On the basis of phenotypic properties and phylogenetic distinctiveness, the milk isolate is classified as a new species in the genus Epilithonimonas, for which the name Epilithonimonas lactis sp. nov. (type strain H1T =LMG 24401 T =DSM 19921T) is proposed.
