A Gram-staining-negative, motile, aerobic and rod-shaped bacterial strain, PAMC 27157 T , was isolated from a melt pond on sea ice in the Chukchi Sea. Phylogenetic analysis of the 16S rRNA gene sequence of strain PAMC 27157 T revealed an affiliation to the genus Aureimonas with the closest sequence similarity (96.2 %) to that of Aureimonas phyllosphaerae. Strain PAMC 27157 T grew optimally at 30 8C and pH 7.0 in the presence of 3.5 % (w/v) NaCl. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylmonomethylethanolamine, sulfoquinovosyldiacylglycerol and an unidentified aminolipid. The major cellular fatty acid was summed feature 8 (C 18 : 1 v7c and/or C 18 : 1 v6c, 83.1 %) and the major respiratory quinone was Q-10. The genomic DNA G+C content was 69
