abstract= A novel bacterium, designated R14M6T, was isolated from deep-sea sediment collected from the Ross Sea, Antarctica. Cells are Gram-stain-negative, aerobic, pale yellow, short-rod-shaped, polar-flagellated and aggregate-forming. Growth occurs at 4–36 °C, pH 6.0–8.3, and in 1–15 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain R14M6T clustered together with Aurantimonas endophytica EGI6500337T and fell within the genus Aurantimonas . The 16S rRNA gene sequence of strain R14M6T shared similarity with A. endophytica EGI6500337T (99.15 %), A. manganoxydans DSM 21871T (97.73 %), A. coralicida DSM 14790T (97.58 %) and ‘ A. litoralis ’ KCTC 12094 (97.51 %). The DNA–DNA relatedness values between strain R14M6T and A. endophytica EGI6500337T, A. coralicida DSM 14790T, A. manganoxydans DSM 21871T and ‘ A. litoralis ’ KCTC 12094 were 36.9±4.5, 27.6±2.8, 29.6±1.2 and 25.2±2.4 % respectively. The major fatty acid of strain R14M6T was C18 : 1 ω7c. The major polar lipids were phosphatidylcholine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and an unidentified aminolipid. Strain R14M6T contained Q-10 as the dominant isoprenoid quinone. The DNA G+C content of strain R14M6T was 67.4 mol%. Based on the phylogenetic, physiological and chemotaxonomic analyses, strain R14M6T represents a novel species of the genus Aurantimonas , for which the name Aurantimonas aggregata sp. nov. is proposed. The type strain is R14M6T (=GDMCC 1.1202T=KCTC 52919T).,
