A Gram-negative, non-motile, aerobic bacterium, designated strain IP7T, was isolated from seawater at the shore of the Incheon Eulwang-ri beach, South Korea. Cells of strain IP7T are straight or slightly rod-shaped and colonies are round, convex and orange-yellow. Strain IP7T is flexirubin-negative, mild halophile, catalase- and oxidase-positive, and produces a yellow-orange carotenoid pigment. Growth is optimal at 30°C, pH 7–9, and 2.0–4.0% NaCl (w/v). On the basis of 16S rRNA gene sequence similarity, strain IP7T is affiliated with genus Aestuariibaculum in the family Flavobacteriaceae, the closest relative being Aestuariibaculum suncheonense SC17T (98.3% sequence similarity). The DNA G + C content of the novel strain is 37.4 mol%. The only quinone is MK-6 menaquinone. Iso-branched C15:0, iso-branched C15:1 G, and iso-branched C17:0 3-OH are major fatty acids. The major polar lipids are phosphatidylethanolamine, an unidentified aminoglycolipid and two unidentified glycolipids. The DNA-DNA hybridization value of strain IP7T with Aestuariibaculum suncheonense SC17T is 28.87%. Based on the collective DNA-DNA hybridization, biochemical, phylogenetic and physiological data, we report a novel species of the genus Aestuariibaculum for which the name Aestuariibaculum marinum sp. nov. is proposed. The type strain is IP7T (= KCTC 52521T = JCM 31725T).

Abstract

A Gram-staining-negative, non-motile, catalase- and oxidasepositive bacterium, designated strain I-15T, was isolated from a crab of the Yellow Sea, Korea. On the basis of a 16S rRNA gene sequence analysis, strain I-15T was shown to belong to Bacteroidetes, related to the genus Aestuariibaculum. Sequence similarity between strain I-15T and the only type strain of the genus Aestuariibaculum, Aestuariibaculum suncheonense SC17T, was 96.7%. Strain I-15T grew at 0.5–6.0% (w/v) NaCl, at 10–42°C and at pH 4.5–8.0. It could hydrolyze starch and Tweens 80. Menaquinone-6 was the only respiratory quinone, and summed features 3 (C16:1 ω7c/C16:1 ω6c) (16.4%), iso-C15:0 (15.6%), and iso-C15:1 G (12.6%) were the major cellular fatty acids. The major polar lipids were phosphatidylethanolamine, two unidentified aminolipids and two unidentified lipids. The DNA G+C content was 39.0 mol%. Polyphasic data allowed genotypic and phenotypic distinction of strain I-15T from the only validly published Aestuariibaculum species. Therefore, the organism is considered a novel species of the genus Aestuariibaculum, for which the name Aestuariibaculum scopimerae sp. nov. is proposed. The type strain is I-15T (=KCTC 32459T =JCM 19486T).
