A bacterial strain, designated KMM 6177T, was isolated from the sea urchin Strongylocentrotus intermedius and subjected to a polyphasic taxonomic investigation. The bacterium was found to be heterotrophic, aerobic, non-motile by gliding and orange-pigmented. Comparative phylogenetic analysis based on 16S rRNA gene sequencing placed the marine isolate in the genus Bizionia, a member of the family Flavobacteriaceae, with 16S rRNA gene sequence similarity of 94.9–98.6?% with recognized Bizionia species. Strain KMM 6177T grew at 4–39 °C and with 1–8?% NaCl. It produced alkaline phosphatase, catalase and oxidase and hydrolysed aesculin, gelatin, DNA and Tween 20. The predominant fatty acids were iso-C15?:?1, iso-C15?:?0, iso-C15?:?0 3-OH, iso-C17?:?0 3-OH and a summed feature (comprising iso-C15?:?0 2-OH and/or C16?:?1?7c). The DNA G+C content was 34.4 mol%. A combination of phylogenetic, genotypic and phenotypic data clearly indicated that strain KMM 6177T represents a novel species in the genus Bizionia, for which the name Bizionia echini sp. nov. is proposed. The type strain is KMM 6177T (=KCTC 22015T=LMG 25220T) |
