Cells were moderately halotolerant, catalase- and oxidase-positive rods. Growth was observed at 5–40 °C (optimum, 25 °C), at pH 5.5–9.0 (optimum, pH 7.0–7.5) and in the presence of 1–11 % (w/v) NaCl (optimum, 2–4 %). The major cellular fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C17 : 1ω9c and anteiso-C15 : 0. The polar lipid pattern comprised phosphatidylethanolamine, four unidentified aminolipids and three unidentified lipids. The G+C content of the genomic DNA was 42.3 mol% and the only respiratory quinone was menaquinone 6. Phylogenetic inference based on 16S rRNA gene sequences showed that strain BS12T formed a tight phyletic lineage with members of the genus Gramella . Strain BS12T was most closely related to ‘ Gramella jeungdoensis’ HMD3159 with sequence similarity of 97.5 %, but the DNA–DNA relatedness value between the two strains was only 22.1±2.2 %. On the basis of phenotypic and molecular features, strain BS12T was shown to represent a novel species of the genus Gramella , for which the name Gramella aestuarii sp. nov. is proposed. The type strain is BS12T ( = KACC 16188T = JCM 17790T). An emended description of Gramella echinicola is also proposed., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.048694-0
