Abstract
    A novel aerobic, non-motile, Gram-negative bacterium, designated AS06/20aT, was isolated from coastal waters of the Adriatic Sea and subjected to polyphasic taxonomic analysis. Cells were rod-shaped and formed non-pigmented punctiform colonies on agar plates. The novel isolate grew heterotrophically on a variety of carbon compounds, including organic acids, carbohydrates, polyols, amino acids and complex organic substrates. Cells grew at 15–33 °C (optimum 30 °C), pH 6.5–8.5 (optimum pH 7.5–8.0) and between 2 and 6 % (w/v) NaCl (optimum 2 %). The dominant fatty acids (>5 %) detected in strain AS06/20aT were iso-C15 : 1 G, iso-C15 : 0, iso-C15 : 0 3-OH, iso-C17 : 1{omega}9c and iso-C17 : 0 3-OH. The major respiratory quinone was MK-6. The G+C content of the genomic DNA was 38.9 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain AS06/20aT fell within the family Flavobacteriaceae in the phylum Bacteroidetes. Comparative 16S rRNA gene sequence analysis indicated that strain AS06/20aT was most closely related to members of the genera Zeaxanthinibacter and Robiginitalea, sharing 92–93 % 16S rRNA gene sequence similarity with representatives of these genera. It is proposed, from the results of the polyphasic taxonomic analysis, that the strain should be placed in a new genus, Eudoraea gen. nov., with Eudoraea adriatica sp. nov. as the type species. The type strain is AS06/20aT (=DSM 19308T=CIP 109577T=OOB 358T).
