Popis: | A Gram-stain-negative and strictly aerobic, moderately halophilic bacterium, designated strain S1-47T, was isolated from estuary sediment in South Korea. Cells were non-motile rods showing oxidase- and catalase-positive activities. Growth was observed at 10–30 °C (optimum, 25 °C), at pH 5.0–8.0 (optimum, pH 6.0–7.0) and in the presence of 0–6.0 % (w/v) NaCl (optimum, 2.0 %). Strain S1-47T contained summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0 as major cellular fatty acids and ubiquinone-10 as the sole isoprenoid quinone. Phosphatidylethanolamine, an unidentified aminolipid, an unidentified phospholipid and three unidentified lipids were detected as polar lipids. The G+C content of the genomic DNA was 69.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S1-47T formed a tight phylogenetic lineage with Albirhodobacter marinus N9T. Strain S1-47T was most closely related to Albirhodobacter marinus N9T with a 99.4 % 16S rRNA gene sequence similarity. DNA–DNA relatedness levels between strain S1-47T and the type strain of Albirhodobacter marinus were 49.8–52.2 %. Based on the phenotypic, chemotaxonomic and molecular features, strain S1-47T clearly represents a novel species of the genus Albirhodobacter , for which the name Albirhodobacter confluentis sp. nov. is proposed. The type strain is S1-47T (=KACC 18804T=JCM 31536T). |
