abstract= An aerobic, Gram-stain-negative, short rod-shaped, non-motile and non-sporulating bacterium, designed strain 8-1bT, was isolated from seaweed collected from the intertidal zone of Zhoushan sea area, East China Sea. Strain 8-1bT grew at 4–39 °C (optimum, 28–32 °C) and at pH 6.0–9.5 (optimum, 7.0–8.5), and with 0.5–8 % (w/v) NaCl (optimum, 1–3 %) and 0.5–10 % (w/v) sea salts (optimum, 2–3 %). Analysis of 16S rRNA gene sequences revealed that strain 8-1bT was related closely to Aequorivita capsosiphonis JCM 15070T (96.7 % similarity). The DNA G+C content of strain 8-1bT was 36.6 mol%. Compared with reference strains, cells of strain 8-1bT showed positive activities for H2S production and utilization of d-mannose, dl-lactic acid, l-asparagine and glycyl l-aspartic acid. The major fatty acids of strain 8-1bT were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G and iso-C17 : 1ω9c. The main respiratory quinone was menaquinone 6. The polar lipids of strain 8-1bT consisted of phosphatidylethanolamine (PE), three uncharacterized aminolipids (AL1–3), four uncharacterized glycolipids (GL1–4) and five uncharacterized lipids (L1–5). Based on the phenotypic and genotypic characterization, strain 8-1bT represents a novel species of the genus Aequorivita , for which the name Aequorivita viscosa sp. nov. is proposed. The type strain is strain 8-1bT ( = CGMCC 1.11023T = JCM 18497T). Emended descriptions of Aequorivita antarctica and Aequorivita capsosiphonis are also presented.,
