Maribacter stanieri sp. nov., a marine bacterium of the family Flavobacteriaceae

Abstract

The taxonomic status of two novel heterotrophic, Gram-negative, gliding and yellow pigmented bacterial strains was established in this study. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that the strains formed a distinct lineage within the genus Maribacter, a member of the family Flavobacteriaceae, with sequence similarities of 96.3–98.5 % to recognized species of the genus Maribacter. The maximum growth temperature of the strains was 35 °C and they required NaCl or seawater for growth. They hydrolysed aesculin and gelatin, reduced nitrates to nitrites and produced acid from carbohydrates. The DNA G+C contents of strains KMM 6025 and KMM 6046T were 36–37 mol%. On the basis of phenotypic, genotypic and phylogenetic characteristics, it is suggested that the new isolates represent a novel species of the genus Maribacter, for which the name Maribacter stanieri sp. nov. is proposed. The type strain is KMM 6046T (=KCTC 22023T=LMG 22581T).
